I do what I love to do at the moment. If I wake up tomorrow and decide I want to dance that's what I'd do. Or design clothes. I think I'd throw myself into whatever I'm doing now. It's not about abandoning what I was doing before or giving up. It's about knowing that if I die tomorrow I lived the way I wanted to.
There is no need to worry about mere size. We do not necessarily respect a fat man more than a thin man. Sir Isaac Newton was very much smaller than a hippopotamus but we do not on that account value him less.
