Backing it up

I've been following Epic Camp like a junkie and Scott Molina posted this. this is awesome.

"Resilience.
This is one of the main physical and mental characteristics one needs to be successful at this sport.
You have to work through plateaus.
You have to train when injured sometimes (often for older athletes).
You have to train when sick sometimes.
You have to train when tired or crappy weather threatens to de-rail you.
You have to train when you just don't feel like it.
You have to do it consistently week after week, year after year.
This is what Cam Brown calls "backing it up".
