Luck is a dividend of sweat. The more you sweat, the luckier you get.
Humans are meant to work and sweat to earn a living. Those that try to get rich quick, or live at the expense of others, all get divine retribution somewhere along the line. That's the lesson. Unfortunately, we quickly forget the lessons we've learned and then we have to learn them all over again.
I'm sweating like a hooker in church.
Cheerleaders - we don't sweat, we sparkle.
Nobody ever drowned in his own sweat.
The more you sweat in peace, the less you bleed in war.
I swear I'm sweating like a sinner in church.
