It's great to have curiosity and confidence in yourself, but similar to what everyone on here is saying (from what I read), you absolutely need to devote your life to golf if you want to get anywhere near an elite competitive level of play. Take Tiger Woods, for instance. He's been playing since he was 3 years old, and when he was 3 he could shoot a 48 on 9 holes. Considering you're 22 years old and have never played an actual course, if we do the math here (and if it actually translated) you won't be playing competitively at Tiger's level (if you practice, play, practice, play every day) until you're like in your mid 50s to early 60s. And taking into account the capacity at which a child's mind can learn things, you are in a way, generally speaking, doomed. That doesn't mean you shouldn't set your sights on something though. If you want to play professionally and think you can do it, by all means, go for it. It's just going to be harder than you think. Research the topic, set some goals, and begin. Sure, there are naturals to the game, so to speak, but even they had to work pretty damn hard to get where they're at. Me, I'm 21 years old, have been playing since I was 10 and still don't get under par. I played competitively in high school for 3 years, and even that is 150% different from hitting balls on the range, or mini-golfing. You have to start somewhere though, and maybe with your research you should look into purchasing some golf books and reading up on how to do things, different philosophies, what have you. Don't take comments personally-- you put yourself out there with an honest question, which is very admirable. Take care.
