Three Things

Three things cannot be retrieved:

The arrow once sped from the bow,

The word spoken in haste

The missed opportunity.

— Idries Shah, “Caravan of Dreams,” citing Ali the Lion, Caliph of Islam

Don’t make a threat that you’re not willing to make good on. And think over your words; only fools believe that people who take their time when speaking are slow.

As for opportunities, I don’t think it’s so dangerous to miss them. There are new ones every day.
