I say do what is in your control, if you can start up I say go for it the sooner you start up the better off you'll be. I didn't start thinking about my future till I was 20 and remember this important advantage. YOU ARE 16 AND YOUNG. Lots of people don't think this way till they are in their late 20's, 30, 40', or more. When you're starting up your future I say
1. Be patient
2. Be consistent
3. Stay motivated
4. Find people who got what you want
5. If its useful keep it and if its useless drop it.
