I can do #5 and still not be the best golfer where I work.
As has been said a thousand times before:
1. Win your Club Championship
2. Become the best player in your area.
3.Become known as one of the best players within a hundred miles
4. Win some serious amateur events in yoiur area as the favourite.
5. Be able to score legitimate sub par scores on decent courses in fair conditions.
Then.........you start to think about maybe becoming a pro.
There will be a thousand guys who would beat you by 5 shots on any day of the week even if you are off +1, but that's OK.
Let's not put the cart before the horse.
There have been a dozen threads exactly like this. All of them start with a beginner who wants to be a pro.
I have NEVER read one where someone has achieved ONE of the things I listed above and wonders about how good they are.
Desire is one thing - but don't think that every young man with a passion for golf doesn't dream about being a pro.
Don't be suckered in by the "if you can dream it you can be it " nonsense. You have to do it.
Get back to us when you're a legitimate scratch player. By that time you'll be one of the better players at your club.
Read Paper Tiger by Tom Coyne first.
