How to live to old age in the Mopar hobby

I'm a shining example of this... of course I always was in to cars and always fixed my own cars, but never really got into them too deeply. I took high School auto shop and all that and majored in it as well. Work lots of skilled jobs, but always fix my own cars. And this duster when I got it 6 years ago I really embarked on a total disassembly and reassembly many many times on it. I've changed everything. I could have just kind of put it together and made a huge profit by now but I'm upside down into it like you wouldn't believe! LOL loving every minute of it and of course and my wife knows every penny that's been spent. But the education that it gave me... I now for a living help people restore their cars from all the knowledge I gained working on it.. It not only pays well, but I do what I love...
Where/how are you doing that? Do you have a shop? Are you going to peoples houses to help them? Are you bringing projects back to your house?
