Where is the smiley in my PFP?

Play Longer Time Controls...
For many at the beginner-novice level, speed chess tends to be primarily an exercise in moving pieces around faster than your opponent while avoiding checkmate, in hopes that his/her clock runs out sooner than yours.  And/or hoping to notice and exploit your opponent’s blunders while hoping they don't notice yours.  The reason for this is that in speed chess there is little time to think about what you should be doing.

It makes sense that taking more time to think about what you should be doing would promote improvement in your chess skills and results.  An effective way to improve your chess is therefore to play mostly longer time controls, including "daily" chess, so you have time to think about what you should be doing.

This is not to suggest that you should necessarily play exclusively slow or daily time controls, but they should be a significant percentage of your games, at least as much, if not more so than speed games which, while they may be fun, do almost nothing to promote an understanding of how to play the game well.
