Everything. If you can't honestly just enjoy a massive steak burrito with everything on it for what it is... You just aren't going to find much happiness in life.
I thought the matrix was going to be the most amazing movie ever from the build up I got from people... I then watched it and was disappointed because my expectations were out of whack whereas if had been surprised by the matrix and had no preconceived notions about it, I might have found it amazing. Go into everything in life with low expectations and you will be happy. Expect chipotle to taste like garbage and then stand back and see the salvation of the burrito. Chipotle is great, but don't let my experience raise the expectation...
