Age eventually introduces you to the reasons behind rules you once considered unnecessary.

Rules that once seemed arbitrary tend to have a story behind them, usually a bad one. The procedure exists because something went wrong, the caution exists because someone was hurt, the boring convention exists because the alternative failed loudly enough for people to change. You do not see any of that until you meet the situation the rule was written for.

Before removing a constraint that seems pointless, find out why it was put there. If nobody knows, that is a reason for caution rather than confidence. Some rules are genuinely obsolete and should go; the ones that survived usually did so for a reason worth learning.
