life question

[weemanch]

Okay i'll first give background info on me before i jump straight to the question.
Background info: okay i am currently about to start my first year of college. For aviation mechanic, i got to this point because was in a bad motorcycle accident and had worked in factorys, before this as if i should possibly be doing some other type of career over this aka drive semi.

So question: how did you know forsure what you wanted to do n life or was it just following in fathers footsteps? Since i am unsure of which route to go really keep second guessing my self which i know its not good to play the what if game but it is my career my life, that i am pplayin that with.
