> because I don't know what I want.
Only very few people know what they want at your age. So no need to worry about it.
Since you are already in college, focus on completing it properly and at the same time, you definitely need a goal. Without a goal and a map & plan to get to that goal, you'll just go around & around.

I just finished reading the book The Magic of Thinking Big, and it talks a lot about this concept, especially with regards to believing something is possible. If you start off with an attitude that something is impossible, you put your mind at a disadvantage. If you can convince yourself that something is possible, your mind will start coming up with ways to make it happen.
I see this a lot in my daily work. If there is a task that's been bothering me, a lot of times if I give it a fresh look on a new day, with the attitude of "There is a way to figure this out and take care of it," before I know it, I've thought of a solution.
Today, I've been feeling bad, and not getting much done, and feeling bad about not getting much done, and I'm stuck in a cycle. I need a way to break out of the negativity cycle and get back to positive thinking in times like this!
I can not stress this enough: exercise and attitude. Exercise is pure awesome fun, always push yourself and see what you can do with your body. You will always come out as a winner. Now, for attitude, PERSPECTIVE IS EVERYTHING. And one way to gain is to focus on your attitude. Attitude plays everything, keeping on track of homework, gym, ambitions and goals and everything you want to work for. Highly recommend reading "The Magic of Thinking Big".

It might be able to change your opinion
You need stronger motives. Your selfishness is way too strong. You have to live and strive for others, you have to figure out: What kind of life do I want my parents to have in their late 70s? What kind of opportunities do I want to give my future children? What kind of man do I need to become for my future wife, to give her all the desires of her heart and treat her like a princess? What kind of impact do I want to leave on my community? How can you help anyone else find a great job if you can't? How can you help someone have a passionate, fulfilled marriage if you can't have one? How can you help someone be filled with energy and vitality if you're eating cheetos and watching netflix?

Take your eyes off yourself, there is too much crap in this world and too many people hurting to not go out there and lend a hand.
I can't tell you exactly what you can do to achieve the level you wish to be, because I'm not you and even if I understand the context, I won't be able to give you YOUR game plan, because that is YOURS to create. Also we grew up differently with different experiences that shape us as individuals so I don't have a direct answer for you.
But what I can do for you is to recommend these books for you because these are the book I start to read to start my journey of finding out who I really am and change my life to one that I'm proud of and love.
