The most important part, is having an exit strategy. This means always having a way to get back UP if you get DOWN. This can be a helping hand from a person, having a fully loaded wheelbarrow to grasp or having a tree that you can lever yourself up with. Having an exit strategy means you won't have a "Help, I've fallen and I can't get up!" moment. It also means you'll more than likely be able to get yourself to the ladies' room before you dribble.
