I"d rather have 5000 chips to start. This week, after losing 1500 in one pot early on, I felt I was basically going to be committed for my tournament life if I played any more pots.
I managed to go from having 22K and being top 20 to out in 5 minutes, pretty much. Every time I was in a pot, I got horrible boards and got shoved on. Eventually I went out putting my last 7K in with QQ vs AJ on an AJx board, but I was just fed up with it (and hungry!) by that point.
