Try this from my Army days:


Slow is Smooth.

Smooth is Fast.

This comment:

The "slow is smooth, smooth is fast" saying has its origins in the military. With that context the meaning is fairly obvious: moving fast, or rushing it, is reckless and will likely get you killed. If you move slowly, carefully and deliberate however, you are really moving as fast as you can without needlessly increasing the risk on your life. (Or that you will get it wrong.)
