As a child, I found myself surrounded by incredible whitewater paddlers and slalom athletes. Richard Fox, 5 Time Slalom Kayak Champion, once told me that most people had it all wrong. *insert mild British accent here*
“Its not practice that makes perfect, its perfect practice that makes perfect.”
For some reason that piece of advice has always stayed with me 
especially when it applies to rescue training, instruction, and practice. It can be as simple as ALWAYS making sure a carabiner is up facing the next load, making sure you wrap your prussiks the same way every time, tying knots properly, pulling out enough tail in your throw bag for a margin of error, or putting yourself on the correct side of a bight for a belay. The time it takes to deliberately follow good habits is the time it takes to ingrain those habits in your muscle memory so that when you need to use them you can expect your body to preform. Even now while teaching I if I clip in a carabiner to a rope, I will take it off and change it to attach it properly not just for my student’s benefit of always seeing it done right, but also to continue to practice those perfect habits.
So the next time you have your Z-Drag practice in your backyard, during lunch, or waiting for the shuttle make sure you practice perfect!
