How did you get that big stack?

[LoveMyAces]

There was a recent question about how many times the buyin was your biggest stack. My question is how did you win all those hands? There was a player on party with 26 buy-ins this morning. I see these big stacks quite often and wonder if there is a strategy to get there or is it mostly luck? I notice that most of the players with the big stacks raise a lot more but when I try this I always miss my hand about as far as it can be missed and end up throwing away raise after raise. What is the big stack secret?
