We are all simple people, but it doesn't mean our dreams must be. I had a dream to climb Everest; I just never imagined that I would be doing it alongside Kenya's newest hero.
I'm not fearful of not reaching Everest's summit. I have a possibly tongue-in-cheek theory that all motivations in life can be distilled down to fear. It is omnipresent, so you might as well be scared about something worthwhile.
