Life In 19x19

This is a four stone game I played today against someone I used to play quite often but haven't met up with in about a year. I played the white stones and I feel like like a missed some good opportunities in this game. Looking for a little help with handicap fuseki strategy and the proper mindset going into handicap games.

Even in handicap games you have to have some patience and not be so aggressive. Moves like L10 and K11 are too hasty and in the end cost you the game.
