Have you ever stopped to think of all the things, events, circumstances, etc. that you're exposed to every day that can be irritating? You get stuck in traffic... you catch up on the day's news... you drive away from the drive-thru lane only to realize that they forgot your fries... and on and on...
What would it look like to go just ONE day without getting irritated? What would it take?... and what would be the benefit?
