I know it's really square but I'm one of those people who piles on the factor 50 as soon as I'm outside.
I couldn't sustain myself if I skimped on food - I work 16-hour days, I need the energy, I can't afford to be stingy on what I eat.
I swing between procrastination and being really thorough so either way things aren't getting done quickly.
I was very much into science when I was young - I wanted to be a marine biologist, then I wanted to be a doctor, and then something else, I was always changing.
