Is becoming a mechanic worth it?

I am currently unemployed. I am good with my hands and fixing stuff but I am terrible with most people. Honestly I think I may have a autism spectrum disorder seeing how I can be so socially autistic. At the end of high school I ended up taking graphic design in school but it didn’t work out in the end. I also took auto in high school and something tells me that is what I should have done all along. However a lot of people online say its not worth pursuing. Others say if you love doing it, do it. I just would like some real insight. If I were to go to an auto mechanic school or motor cycle mechanics school will it be worth it if I like it?
