Depends. Some people just go after more money, Bigger house payments, bigger car payments, upgraded hotel rooms on vacation... Stuff that doesn't matter much in the big picture.
Money's easy to get. Time's absolutely limited. Planning for a grand retirement you may never reach is foolish. I could have literally doubled the money I've made by making different decisions in life. That would have meant working lots of overtime, working out of state, and being a gypsy jumping from company to company... I'd have missed my daughter growing up, worked my ass off, and had slightly nicer stuff and a fat bank account for... I don't know what. Big numbers to count I guess.
I wouldn't change a thing that significantly affected my bottom line. If I could go back, I'd do things exactly the same way.
