Well, if you don't enjoy it anymore, then I can understand. Maybe some time away would be good... Get a fresh perspective. But, at least do this: Before you sell all your tools, take a good look at your work, and your progress at the art. You've got talent. Don't "bury it"... Use it. It's a gift.
I fully understand the money aspect. I was a part time builder until I lost my full time day job in Nov. 2011. I havent had a real paycheck since. At times I have rhetorically asked myself "why am I still doing this". If it wasnt for my wife believing in what I do, I guess I wouldn't be doing it. I just turned 49, and I finally LOVE what I do. It takes a lot to "make it" as a full time luthier. I'm still at the stage where everything I make goes right back into material & tools. Now I have a shop with all the bills that go along with it. But, I'm right on the edge of things finally breaking loose. I just picked up a customer today that wants to carry my guitars as their premier brand.
Sometimes it helps to analyze yourself, and what you are looking to achieve by building. For some guys it's money, others for the art, others do it for the fun. Some do it for their ego. Any way you do it, one thing is the same for everyone. Perfection is un-obtainable. For a long time the best I could do was just not good enough to satisfy me. Then I realized that striving to continually improve is the only way to do this without it driving me crazy. Now I strive for excellence. Frankly, sometimes I'm disappointed in myself. I've burned some really nice guitars. But, I refuse to let that stop me.
Whatever you decide to do between now and next year, I hope you do it without regret...
