I remember thinking that a girdle was barbaric, and that never in a million years would I treat myself like a sleeping bag being shoved into a stuff sack. Never! Instead, I would run marathons and work out and be in perfect shape and reject the tyranny of the girdle forever.
Like writing, running is so much about mind over matter. There are times when you have to override the discomfort and keep pushing. That capacity to endure and then prevail is just amazing.
I think the responsibility of running a huge business, which happens if you become a successful designer, probably makes you more careful.
