-Focus in more on the games/genres I actually love. Too much branching out, trying to be part of the zeitgeist and play as many of the hyped games as possible is recent years has led to wasting too much time on games I wasn't liking much, or thought were just ok, instead of playing games I was truly enjoying.
-Related to the last one, abandon games and move on to another one quicker if I'm not loving a game.
