Please give “The Gambler” by Kenny Rogers a listen.
Rarely will you find such solid advice in a popular song of a few years ago. There is a lot more to it, but this brief excerpt captures the wisdom within the song:
“You've got to know when to hold 'em
Know when to fold 'em
Know when to walk away
And know when to run…”
Indeed there’s much wisdom in those few lines. Enjoy and learn!
