you can say that quote all you want but as i remember lowe was a bad ass who took on insanely hard challenges. it's not like he was just out cruising on 5.8 all the time.
there is nothing wrong with the desire to climb harder. It takes a lot of hard work and dedication, so whatever it takes to motivate you. there is also nothing wrong with being competitive, some people are not into it(there the one's lying to themselves) and some are. if you are content to just cruise on stuff within your comfort range fine, but i want to do new lines. and the harder you climb the more great lines are open to you. i am tired of seeing all this incredible stuff and thinking oh that is too hard for me.
what climber does not have ambition?
