I echo the others who say to get outside and moving - it's a lot easier than being in a confined space.
One other thing, DON'T LOOK DOWN at your feet when you do it!!! If you do, you'll swerve all over and crash and fall - I know from experience
I also rest my foot on the pedal after I unclip until I'm ready to put it down - I just put my foot a little further up so the pedal rest towards the middle/back half of my foot. Sometimes my cleats will re-click in, so I try to keep the cleat just in front of the pedal so I dont reclip in.
