For that you need a partner you don't have to pay, and preferably one who is more advanced than you. True partnerships do not include signed damage waivers or require liability insurance. Not only is it counterproductive to try to mask ability or skills, it's downright dangerous. Climbers ascribe to the rule that a system is only as strong as its weakest link. In the quest for clarity and safety, climbers constantly compare and share information and techniques about routes, conditions, equipment and each other.
Experience is hard-earned.
Experience makes you a teacher. And anyone who climbs more than a few seasons will find themselves teaching someone else. Whenever I teach anyone, young or old, a new skill, my own perspective becomes refreshed. There's nothing quite like sharing in another person's thrilling achievement to remind even the most jaded, crotchety old alpinist what the pure unchecked feeling of climbing is like. After leading groups of wannabe rockjock dudes in their 20's, women friends and teenagers skyward, I've learned that climbing is a wonderfully egalitarian sport that transcends age, gender, language and even disability.
