I recommend playing in a G/30 tournament regularly, and then try to play one “slow” tournament every month or so.  I find that people who only play slow time controls (like G/120 games that last up to 4 hours) take their extra time for granted… and they just end up walking around during their games, or watching other games. People who play G/30 and G/120 get experience, but they also appreciate the long time control.
