I believe that a hill, an actual, up it goes hill, has a personality. The big one's, the one's that you see from afar, are absolute *%$holes. They want you to fail and they do everything they can to make it happen. They gloat and belittle you at every chance. That's why, when I'm running or cycling, I determine myself to kick it up every big hill. I don't want to let it get the better of me. When I know that a hill is coming, I start thinking about it's personality and push on to get there and run it down. When I win, the hill gets a little bit smaller. The more times I win, the smaller it gets. I have a hill near my house that my wife and I call the 'demoralizer.' It has a nonchalant, almost innocent look but once you get on it, wow, the legs and heart have to work to win. I've taken a few licks from that hill over the years but it's getting a bit smaller every time.
So, think about the hill, or hills, that you face, consider their personality, and beat it out of them. It can be actual hills, or it can be metaphorical hills like injury, fear, mid-terms, whatever, just don't let them get the better of you.
