I've sure learned a couple of
wrong ways to do it, where the thrill of the chase for parts made of unobtanium (especially in the olden days) became more important than actually working on the car.
Then came the one where it just needed
everything - and I couldn't afford
everything - so I basically got paralyzed from doing
anything with it.
This one, life events sort of led me to the most enjoyable way to fix one up - one step at a time.
I started with one that had the parts done that I couldn't do (paint, metal, etc.) and did all the mechanicals, electricals, plumbing, whatever - but always one small portion at a time. I made mini-projects out of each one, bite sized tasks that someone recovering from cancer surgery could handle.
That worked like gangbusters - it kept the budget reasonable (buying parts only as I went) and I got little instant gratifications along the way to keep me motivated.
That's the key for most folks who don't have unlimited budgets I think - along with finding like-minded people to interact with, seek counsel from, get encouragement from - like
FBBO!
