I say the same thing to some friends from grade school that play occasionally; play for fun only until you start playing weekly at the least. Then you can worry about improving. Until then it's just a fun walk in the park drinking with friends. I advise them that until you play regularly, breaking 100 is awesome, and then every 20-25 rounds you play you can hope to improve 5 strokes on average until you hit the low 80s; then it gets much harder.
