Two things - determination and dedication should be a part of your life.
Study for you and your goals.
Study for your parents they are spending bucks.
Do not think of harwards, PhDs, majors. Forget the word etc. in your career.
Choose one achieve one.
One target, one goal = successfull.
Ignite that spark in your body.
A rocket reaches to top by the fire that makes it fly high, try to ignite that by choosing one target being with the people of same target, forget all distactions, do not stop gaming but have some priorities for your studies.
And believe me if you balance all the aspects your future would be rocking.
