When you spend as much time in solo queue as I do, it's very easy to get caught up in the amazement of how bad other people can be at this game. This can sometimes overshadow the things YOU need to get better at. It's good to stop and reflect on your own gameplay every once in a while, in order to improve as a player.

For example, I need to get better at last-hitting when I take boots and 3 instead of Doran's.
