If your young and want to get on tour these days you need:
1/ a top top coach, such as lynn blake, leadbetter, harmon, or some other really experienced coach
2/ equipment as good as what the tour pros get, perfectly fitted drivers, irons, wedges
3/ Parents with lots of money
4/ You ahve to know the right people
(obviously you need the talent, but if you havent got parents who will support you and spend £500 an hour for a lesson with a pga tour standerd coach and will spend money on getting your equipment perfectly fitted i dont think you have much chance)
