How to improve on Blitz Chess

I am currently in the 93% percentile in CC, but are struggling to break through the 80% (+-1300) in Blitz Chess.

Any idea how to improve in Blitz Chess?

Side notes:

I believe that Blitz Chess is the best trainer for life.  Makes you sharp and gets you to make fast decisions.

My own ideas at getting better is:

• Be well rested, 
• Physically fit
• Tactics (via Tactics Trainer) +-1/2 hour per day
• Play in a distraction free environment
• Play opening quick, middle game slow (+-after 7 moves)
