As Steve A. has attempted to explain to you: some people have "mechanical" minds and placing gear is natural to them. Others, that don't, aren't likely to ever "get it".
I know what Steve said and I am sure that he was a good teacher. Some can be natural, but that doesn't means that they can't learn. He probably have student who graduate because they put a lot of work on it.
I think that Adolf Hitler burns book because they think that at the aryuan master race. It is like in a climb, some are better at slab an other at face or over hanging. That doesn't means that you can't improve or that you have to use bolt.
For a child, who fall in 5.7 and, by trying and trying and listening and reading, was able to climb 5.10...with no mechanical minds... on chock, it is a example that if he work as hard in mathematique than he tried in climbing: he can succeed. It is the reason why climbing most be in school. In an exam, you have to wait to know that you made a mistake. In climbing, it is immediately. So a child can understand why it is important to study and that he can have more difficulty than an other, but be able to do the same job with the same money.
Knowing your limits and when to bail, being honest on our limits and humble, climbing for fun...and working hard to improve our skill is more than an example to any
