set a target, everyone have their own Everest mountain to climb on， these target should be the one u r interested and can achieve. start imagine the joyfulness when u climb on that mountain. If cannot pay fully attention on one subject, dare to give up and find another mountain. Learning process would be oppressive if u foster urself doing something that u r not interested in. <---- u can ignore this sentence if u feel that i'm talking crap

just my 2 cents

learn from mistake, expose yourself to the real world, learn from successful people, read more bibliography about successful man- The one thing that you cannot deny is have a heart of passion.
