For me, I've been at it off and on for more than 30 years. All my learning was from books and magazines. Heck, I can't even tell what got me hooked, but I still have the first scroll project I did.
Didn't have internet back then, least ways where I was, but the stuff that's out there is incredible.
Never tried to make money, I would get requests but I would just give them the piece, or donated for silent auctions and such.
The main point is to enjoy your time at the saw and the hardest critic you have is yourself.
