Golf has rules.

Fourteen clubs are the maximum allowed in one player's bag. Any number below 14 is fine, but more than 14 is not. Also, those 14 clubs cannot be changed during the course of one round. You must finish with the 14 you started with.

However, if you begin with fewer than 14, you may add clubs during a round as long as no delay is caused and as long as the club(s) added are not borrowed from another player. There's a penalty for breaking the 14 club rule but I'll leave that to your imagination. Now aren't you glad you know this. Just in case.
