I usually don't dish out quotes but you need some motivation...
When asked about all his failed experiments, Edison said, "Results! Why, man, I have gotten a lot of results. I know several thousand things that won't work.".
Henry Ford once said "One of the greatest discoveries a man makes, one of his great surprises, is to find he can do what he was afraid he couldn't do."
Do what you want to do. It will get you furthest. I work together with engineers and they are, in general like all other people, except they tend to have better insight into a lot of things related to things I have no clue about...
