A lot of times when I play a game, and get to a particular section that either scared me or was too difficult, I would stop playing. Most of the time I revisit the game a couple months/years later, and get past that certain part. Games I have done this with include Halo: CE (for any of you that have played it, you probably could guess which level I had trouble with), Super Mario Galaxy, Super Metroid, Twilight Princess, and a lot more.
