Motivation will come from things that you like and their existence in your life which will ultimately lead to happiness. When it comes to college, see to it that you try to choose the college that always wanted to go or the one that wish to go. After all you must like the place you are going to go for the next 4-5 years of your life. It will certainly matter. The next thing to do is select the subject/major of your choice and more importantly your interest. If things are not going well in your classes and you feel overwhelmed, try changing your major to do something that will make you happy and fulfilled. Don't just take the stream that your friends have chosen just because you want to be with them. Remember you can always make new set of friends. Participate in the class as much as you can. The more you get to learn, grab all the opportunities that come your way. Don't just run after grades and marks all the time. Try to learn and gain knowledge first. Success will automatically run after you. I hope you learnt something at least after watching a hindi movie called: THE 3 IDIOTS!! :)
