First, pick a good quality about yourself. Ask yourself these questions: "What am I good at?" or "What do I like to do?" Whether it is sports or helping people there is always something you can do.
Then, figure out what you want to major in in college. Psychology/Mental Health, Social Work, Business, Culinary Arts, etc. Many colleges have a main "focus point" on what they teach, (i.e. VCU, (Virginia Commonwealth University) is known for being something to do with medical studies. It also teaches many other things such as Business and Culinary Arts.
Once you choose your major, start looking for colleges that will accept you or give you a scholarship. If you play a sport such as basketball or football and if you're pretty good there are a lot of schools that will offer scholarships in those fields.
Don't ever give up on your dream! Always pursue what is good.
