There's a tremendous difference between alone and lonely. You could be lonely in a group of people. I like being alone. I like eating by myself. I go home at night and just watch a movie or hang out with my dog. I have to exert myself and really say, oh God, I've got to see my friends 'cause I'm too content being by myself.
There are many ways to be influential. You can work for politicians or in government and make a difference. And for young women who are interested in running for office, you just have to decide you're going to follow Eleanor Roosevelt's maxim about growing skin as thick as the hide of a rhinoceros, and you have to be incredibly well-prepared - better prepared [than a man], actually - and you have to figure out how you're going to present yourself, and you have to have a support group around you, because it can be really a brutal experience.
Understand that this art has been created by few soldiers in Vietnam to escape or reach: and this is the spirit I'd like parkour to keep. You have to make the difference between what is useful and what is not in emergency situations. Then you'll know what is parkour and what is not. So if you do acrobatics things on the street with no other goal than showing off, please don't say it's parkour. Acrobatics existed long time ago before parkour.
