There are two kinds of “Whatever it takes” behavior.
The first is the obsessive, fanatical kind. The guy who will fix bayonets and charge across any minefield, without giving it a second thought, just because.
This kind of attitude has its uses, especially if one is not phased by a high body count.
(SPOILER ALERT) I prefer the “Whatever it takes” attitude of the Tim Robbins character,Andy Dufresne, in “The Shawshank Redemption”.
Andy does whatever it takes, but he doesn’t set himself a deadline.
He just keeps plugging away, digging his tunnel with his little rock hammer for twenty years, without telling anyone.
Eventually it pays off.
“The redemptive power of persistence”, as it were.
Find meaning. Learn endurance first.
