Don't let your age slow you down. The younger the better. I'm 18 years old, in college and I use all my spare time, when I'm not studying (weekends) to invest thought into my business ideas. When you are taking a shower or on your way to class or even when you're eating, think about your ideas. Also, don't focus so much now on where the start up money is going to come from, just take it one day at a time and eventually you'll come upon a solution.You will be successful in the future so don't worry. Good luck and God Bless!
