I like to drink on the course or not drink on the course - depends on the company and if I have to drive.
I really just enjoy the game of golf.
I don't get too serious about how well I play, I have played great and I have played shitty. I like being outdoors with friends and enjoy the game.
Also, no issues smoking or not smoking on the course. Tobacco I'm indifferent to, sometimes I smoke a cigar (I don't have a humidor), sometimes I have a cigarette with friends who still smoke them, I have no problem smoking a few with friends and then not smoking for a year.
