When you win a game what do you think should be examined?

I am curious what some people think we should look at when we win a game of starcraft. I ask due to Day[9]'s outro for the daily tonight where he mentions we should all go and just play some ladder games and then come away with questions to ask. He mentions to figure out questions to ask yourself and then to hunt solutions for them to apply in later ladder games, applying the "fix one thing at a time" ideology.

An example that maybe you get cannon rushed and do not know how to stop it. Take the question of what to do next time, figure it out and then do it.

I suppose there may be some obvious things but I feel a discussion on personal habits some may have would be cool to speak upon! However, what if we win the game and felt adequate within it, what should we try and take from the game?
