Tight Play

[CubsFanSean]

Hello. Basically, I'm a tight aggressive player whose won enough tourneys that I know I'm just not lucky. I am average I think. I'm trying to move up and be better. The key for me is to become a guy who can get a chip stack and use it to bully. I find myself the guy with 1000 chips and the blinds are 75/150. (esp. in my own home game that I run and people know my image well) Thus, i have to gamble and if I get chips, I usually get 1st or 2nd but I'm leaving it all on that coin flip. Any advice on how to change this up/become a player who accumulates more chips early. Am I too tight early.
