Work hard, get a job and keep flying. In fact get 2 jobs, or 3 if you can fit them in. Live at home with your parents, don't smoke or drink and definitely don't get anyone pregnant, and you'll be a commercial pilot by 21. That's literally all you have to do: You need 200 hours - it takes a long as it takes but do the necessary courses on the way and once you hit 200 you'll have a fATPL. Unfortunately microlights don't count, but have a look at getting your PPL on a TMG, they're cheap and your can convert to SEP easily, plus you can count 30 hours towards your 200.
