I've always made it a habit to act on my feelings of generosity the minute I feel them.
How often do we feel generous, let the moment pass, then don't feel so generous afterwards?
It's pretty common for us to rethink our decisions with time; question our gut:
“Maybe the food wasn't that great, I'd better not compliment.”
“They probably don't need the money, I'd better not give.”
