Truth.
That being said, my ex husband realized early in his career as a lawyer that if he brought lunch to work instead of eating in a nearby cafe as he'd been doing, he'd save himself $7 a day. So he began doing this, and instead of spending that $7, he put it into a special savings account.
After practicing law for many decades and continuing to do this, he now has ten million dollars!
But not from that account. he has ten million dollars because he's a hell of a good attorney and has made a good living at it.
But he maintained that account and I think he ended up with something like $15,000 in it.
