Most of this list is right on. Especially the part of just friggin' doing it, seems like a lot of folk overthink it.

Everyone has their own number-pinning mojo. Some guys like to crumple, some don't. Some use the holes, some pin through the paper. Just make sure you pin it in the correct location and in the correct orientation. Only ask someone to pin your jersey if you would be comfortable asking that same person to pick you up from the airport; yes, it is that personal.

I disagree with #3. In order to ride the fastest overall race you are capable of, there are places to burn matches and places to take it easy; a run-up is a place to burn matches. Same deal with hills, people intuitively know that it's smarter to spend a bit more effort on climbs than on descents, and this intuition turns out to be correct.

Regarding #4, you can waste a lot of momentum if you dismount too soon on a partially rideable climb. Learn to carry momentum into the climb and dismount just before you come to a standstill. There's a bit of a knack to it.
