Being super high in the air made me feel really good, like I had achieved something.  Reaching the top of the climbing wall was a great achievement.  My favourite part of the rock climbing was being lowered down afterwards, knowing I had made it to the top.  As you climbed, some of the grips were smaller and harder to use but other grips were bigger and easier to grab onto.  I set little challenges for myself, like only using the green or red grips.
