You can't get there by bus, only by hard work and risk and by not quite knowing what you're doing. What you'll discover will be wonderful. What you'll discover will be yourself.

I'm greedy for that satisfaction of doing something hard and knowing that, even though I was afraid I couldn't do it, that somehow I can deliver.
