16 is a good age to start training with a local flight school. You can solo at 16, and get your private pilot certificate at 17. Look at the costs of places like riddle and realize that you'll be spending many, many years paying back loans from high-priced aviation academies while making very little as a regional airline pilot.
Try to get a part-time job at your local airport. This will do a couple things for you. One, you'll be exposed to aviation. Two, you may get a discount on flight time or at least get to know the instructors which if you're nice to them may result in a break on dual time. The job may have to wait until you're 18 because of insurance requirements but it doesn't hurt to try.
Most important, have fun, listen, and learn all that you can!
