I’ve got a three other bits of advice: First of all, get really, really good at woodworking. There are lots of people who enjoy it as a hobby. To sell your services, you’ve got to be able to do far superior work or do it much faster than everyone else (preferably both). Failure to do so means competing against hundreds of amateurs who make things for the pleasure of it, then sell their work at cost to fund the hobby. Second, develop great people skills. Most professionals do custom work and few focus on selling a product. Most of them sell a service, and a big part of that is getting customers to enjoy the experience of collaborating with a woodworker to create their dream products. If your customers don’t like you, they can usually save time and money by getting something from an online catalog. People who buy handcrafted items from woodworkers are often attracted to the idea of supporting artisans. The face behind the work is important to them. Last, develop an iron-clad work ethic. In this field you’re directly trading time for money, and that time is very limited. It’s important to be productive, so try to get 40 hours of actual productivity (as in making things) every week. Accounting, phone conversations and social media marketing may be important, but none of them provide an actual paycheck, so they don’t count as productive work.

This is the most fundamental joint in all wood construction. Whenever we have to join a horizontal member (like a chair rail) to a vertical member (like a leg), we need to interlock these pieces at a right angle. By fitting a tenon into a corresponding mortise (hole), we can create a solid 90° joint. Although it may look intuitive to make, achieving a nice, tight fit requires careful technique and practice. There are many ways to make a mortise, but I use a stout chisel designed for that task and simply determine the width of the tenon based on that chisel’s dimension. Cutting the tenon is usually a matter of four straight saw cuts. When you do learn how to lay this joint out properly and cut it to a snug fit, the world of woodworking opens up to you. At that point, you know all the joinery required to build most tables and chairs.
As projects increase in size and scale, there is usually a desire to get a larger table saw, a miter saw, add a small jointer, a router and maybe a belt sander. Eventually, things get out of hand and you are seen at every tool sale, and spend more time online looking at the few remaining tools for which you have not yet found a project that will justify their purchase.

My trusty old radial arm saw is much preferred and the “go to” tool over a table saw. Yes, I realize many question why anyone would ever need a radial arm saw, much less prefer one over a table saw, but I grew up using one and use it for all sorts of projects. I do have a table saw but only use it when I have to when ripping large stock that I can’t get with my radial. Of course all woodworking tools demand respect to avoid serious injury, but my experience is that a table saw demands far more than my good ole reliable, supremely versatile, radial arm saw. Given a choice between one or the other, I’d pick the radial every time.

Building a bookcase or bookshelf is a fairly simple woodworking plan that you can get done in just a day or two. This is also a low-cost project as well and since the project idea is free, you don't have to worry about busting through your budget. Just follow the simple steps in the tutorial and enjoy your own company building a simple bookcase on this weekend.
This is that rare two-for-one deal in which two tools have been effectively made one. The stationary belt sander uses a closed loop of paper that travels at speed around a pair of cylindrical drums. One drum is driven by an electric motor, the other is spring-loaded to maintain belt tension. Powered by the same motor, the stationary disk sander uses sanding disks that spin on a backing plate.
The space behind a door is a storage spot that’s often overlooked. Build a set of shallow shelves and mount it to the wall behind your laundry room door. The materials are inexpensive. Measure the distance between the door hinge and the wall and subtract an inch. This is the maximum depth of the shelves. We used 1x4s for the sides, top and shelves. Screw the sides to the top. Then screw three 1×2 hanging strips to the sides: one top and bottom and one centered. Nail metal shelf standards to the sides. Complete the shelves by nailing a 1×2 trim piece to the sides and top. The 1×2 dresses up the shelf unit and keeps the shelves from falling off the shelf clips.
Multiples of these bookcases can be connected to form a single, larger unit, generally for a built-in application. To do so, simply build them without a face frame, and finish boards that can be used to construct the face frame separately. Then, nail the face frame in place using brads after the cases are installed. To improve the appearance of the face frame joints using this approach, mill the rails (horizontal pieces) so that they are 1/8-in thinner than the stiles (vertical pieces). This creates a nice shadow line and conceals any unevenness at the joint. Also build a single long top to tie all the pieces together. I use plywood with biscuits to span beyond 8″, edge banded with hardwood strips as you have done for your shelves.
Start with the horizontal base rail at the bottom of the bookcase. Hold the rail against the bottom shelf and mark onto the rail the center of each slot cut into the shelf. Then use the biscuit joiner to cut corresponding slots into the back of the base rail. Apply carpenter's glue to the front edge of the bottom shelf, and the rear of the base rail. Insert No. 20 biscuits into the shelf slots, then press the rail into place [ 7 ]. Use a rubber mallet to tap the rail tight. Wipe away any excess glue with a cloth. Attach the valance that runs across the top of the bookcase the same way. (Note: Its bottom edge aligns flush with the case top.)
Plywood shelves are simple to cut, but look a little thin and can sag over time under the weight of books and other payload. I like to apply a solid hardwood strip of at least 1″ thick to strengthen the shelf and give it a more robust appearance. Cut four strips to 3/4″ x 1″ x 36-1/4″ (slightly longer than the shelf itself, allowing you to trim flush later). I attach this strip by simply gluing and carefully clamping for good alignment, gluing the 1″ thickness to the plywood. In the past I have also used biscuits or brads for attaching the strips, but I have found it to be unnecessary, and the method I currently use delivers great results every time. Use a lot of clamps to ensure a good bond between the plywood and edge strip. Carefully force each surface flush as you move from clamp to clamp. If you are careful here, you can save yourself a lot of sanding effort later.
Lots of ways. Woodworking really reinforces my independent nature. Blogs are good. Norm Abrams videos. I have a library of magazines and books with really neat projects which I love to read over and over to get a sense of how other woodworkers think through their creative projects. I have a painter friend with whom I endlessly brainstorm how to finish the final wood project. But really, the wood itself teaches me the most. Each species has different needs. The projects also teach me. Each project is unique in approach, design, and method. I’ve learned to listen and make myself a servant of these things. I come to the shop ready to learn.
Another fine example of remodelling furniture and re-using what already exists in the house.  The bookcase involves using your old kitchen cabinets, and building new shelves on top of them. The final product can also be used as an entertainment unit, housing a television, books and things of your interest along with ample storage to keep other utility objects.
