My Dad take my Guitar away from me, tell me is it fair?

I would say that it is far from fair. Society is taught to think that education is more important then music or your own personal goals. Stick with your dreams and do what's important to you.

I know what you mean, I don't understand why they don't seem to try to understand where children are coming from with our hopes and dreams. But the only thing I could possible think of is its because they want to make sure that you have something to fall back on just in case. I don't want to say that they don't believe in you but sometimes it can be hard to get to your dreams. And you need funds to be able to make it there.

Show your parents how excellent you are, if you are really excellent. Well, parents tends to have a mindset that they have prepare the best for their child. I assume you are not from a music-lover family, and likely your parents are more conservative type. I have some suggestion for you. 1) Firstly, make sure that you are study well. I can't see why studying well and becoming a professional musician can't go together. Don't make a ridiculous reason with "I wanna be a professional guitarist" if the fact is that you don't want to finish your study (at least minimal study - in my country until high school). 2) Talk with your parents about what do you want, and what do you plan for your future for being a professional guitarist. Remember, talk nicely with full respect, they are your parents. Listen to their arguments and slowly talk to them your argument. 3) Try to get someone whom your parents willing to hear. Like, your uncle or your grandpa? Discuss about your dream and your vision with them, and let them talk to your parents. Hope the best for your success. Regards.
