Yeah, the emotional control just comes from experience. Once you've played long enough, you are more able to cut out what is random luck or emotion and really zero in on what wins money. Being able to focus on maximizing those factors (picking good starting hands, playing exploitable opponents, ect.) helps you cut emotional factors out of your game.
Also, while having a big stack does give you more fold equity (because you can threaten everyone's tournament), it also gives you the freedom to wait. Instead of pushing every marginal spot you see, you can wait for good situations to gain chips. And because you have the big stack, people will assume that you are trying to push them around. So often the correct strategy can be to still play your normal solid game.
