At 37, I play less now than I ever have in my life. Of course, I'm not entirely happy about this. I'm averaging roughly 8-10 rounds a year.
I have two young children to raise, a mortgage, two cars, utility bills, medical bills from their births that I'm still paying off, and countless other things. I have never been a member of a club. I simply don't have the time or the money to play frequently. I won't spend more than $50 on a round unless it's at someplace where the green fee is usually double or triple that.
I'm playing the same set of irons I've had since 1993. I've bought a handful of clubs over that time, always used, usually on ebay. I buy a new pair of golf shoes probably once every 5-7 years and never spend more than $50-60... usually I get something on clearance in the winter.
I've said every year for the past five that I'm going to play more this year and I'm going to finally get some new clubs. And at the end of said year, it never happens. Something always gets in the way, like being laid off, losing insurance benefits, missing extended periods of work through illness while working hourly... having to take my kids out of daycare because I can no longer afford it, etc, etc, etc...
My kids are learning the game anyway.... the oldest one is about to turn 5, and he's very much into learning. He already has a good putting touch, but he's not ready to hit a full shot yet.
If nothing else, golf may become an escape for them when they are struggling to make ends meet, much like I am now.
