Setting it all up...

To actually answer your question Windbreaker unlike everyone else saying "play to win," payout structure affects my play a bit. However, if you look at the odds here, say we are dealing with 5 instances of this same hand:
4 times you are going to win this hand and say 75% of the time after you win this pot you will get 1st instead of second. After all you have a massive chip lead... thats 3 times you are going to make $40 assuming you will make second otherwise.
+$120

1 time you will be knocked out
-$40

Total:+$80 in the long run

You did exactly what you should have done.
