@Minia what do you like about bikes in particular though?
I love Design engineering and tuning, looking at how things work and the application of theory.
But more importantly, it's better than most drugs riding motorcycles pretty much wherever!
I've been into Cars forever and recently 2stroke bikes, but when it came to going University I realised that there is so much more to life than just being around motor vehicles all day every day. You have to be passionate, and super geeky into it, but that's okay,
Develop your key skills and interests around them,
that's the best advice I could give you.
Nothing wrong with being a mechanic, but if you became a mechanical engineer, you would be able to be involved in much more detail and greater projects, Motorcycle or whatever... boats are sick too!
My University lecturer once said.., 'look for the things that really turn you on, spark your creativity'
