choosing the right game and right limit

[lamgabejambo]

If I am taking a shot with only 2-4 buy in for a higher game, and I go all AIP with aces and lose to an under pair, is it a bad investment because I'm taking such a huge risk? I know that I would play a lot better in a higher game because I'm more aware of my surroundings, but I can't get a feeling of the variance is just going to crush me. Do I really have to stay at the lower level forever?
