There are many examples of men who have used US collegiate golf as a springboard to reaching the highest level in professional golf - Tiger Woods, Paul Casey, Luke Donald, Nick Faldo and Phil Mickelson to name a few.
The opportunities and facilities available to you when playing collegiate golf are unrivalled. Scholarships provide the opportunity to combine a quality academic education with developing your golf through access to outstanding facilities, first class coaching (often by ex PGA professionals), excellent courses, good competition, not to mention more hospitable weather allowing all year round practice! You will also raise your profile within the golfing world and get to regularly play against the best in the world in your age group and get a taste of what life would be like as a touring professional.
The opportunities are there for the taking. It's up to you to work hard, remain focussed and dedicated to achieving your goal - and you'll have lots of fun along the way!
