Car restoration, well if you are a good business person, yes you can make it work. If you have a job you can make a living, but won't get rich anytime soon. I have two business's now, one is something I love to do, the other is work, and then I have a full time Engineering Position. It depends on what you want to leave as your legacy. I work hard and make a very good living, some people work hard and make enough to eat, others get by and don't work at all. If you work hard enough and do enough research you can be successful, if you half it, then you will be in worse shape that you are right now. So in the end, what can you do and what do you want to do.
