My approach to the game of poker has always been very simple. I am there to play against the bad players, a category that in the lower stakes games is often comprised of casual or "recreational" players. I know that this is where the money comes from in these games and so my attention when playing in them is often entirely focused on this group of opponents.
But just being at the table with a weaker player is not the end goal. Sure, this is a good situation and you will turn a profit in the long run.
