My advice was going to be to purposely a couple of times with them, but you've passed that step.
The only other way I got better was like FACTORe said, practice. Just learn to clip in and out without looking down, making it second nature. Try and do track-stands and balance for as long as possible, when you lose the balance either pedal out, unclip, or fall.
It took me 2-3 rides to get used to them and they make riding much much easier and nicer.
