Here's an interesting graphic from dailymile.com. It shows how I've managed to make running a habit in the last 4 weeks. I really enjoy it, and I have had so much more energy every day because of it. And the last week each day has been plus 32°C and I've been super happy with it.
I found this quote attributed to Alan Alda:
"Be brave enough to live creatively. The creative is the place where no one else has ever been. You have to leave the city of your comfort and go into the wilderness of your intuition. You cannot get there by bus, only by hard work, risking and by not quite knowing what you are doing. What you will discover will be wonderful; yourself."
I like the idea of experimenting and being creative. I have a number of things I want to experiment with - mostly on setting my pace, and setting a running strategy for achieving the best time. But also things like listening to motivational music, and special eating/drinking a few days before running. The biggest thing I want to develop is a desire to move through body warnings and pain to build up my abilities.
