I am amazed by the psychology of hills. One morning, was commuting while listening to my iPod in shuffle mode. Coincidentally, as I hit my first incline, a really thrashing electro-dance track queued up. Without really thinking, I hammered the incline, charged by the music. It wasn't difficult, but it wouldn't have occurred to me to do that before. I would have been afraid of spending my strength
I have also read the suggestion of breaking the hill into parts--focusing on a series of short goals rather than focussing on the top. I also notice that my energy seems to give out about 30 feet from the top no matter how long or steep the hill. Perhaps I should pretend that the top of the hill is another 60 feet away.
