Well, on real rock often climbers do just grab or stand on whatever they can to advance. But it's still interesting because there is usually not much available. The complex route tagging in gyms is so they can simulate the relative lack of "holds" on real rock, while packing a lot of routes into a small space.

Keep with it but be careful--climbing is addictive. You might find yourself quitting your job and living out of a van in Colorado to climb every day...
