if you are on the hunt for your 100 percent you should catalog your weaknesses and vulnerabilities. Don’t ignore them. Be prepared for them, because in any endurance event, in any high-stress environment, your weaknesses will surface like bad karma, build in volume, and overwhelm you. Unless you get ahead of them first. This is an exercise in recognition and visualization. You must recognize what you are about to do, highlight what you do not like about it, and spend time visualizing each and every obstacle you can.
