Parkour teaches you to be sure of what you are able to do.

Obstacles are found everywhere, and in overcoming them we nourish ourselves.

If someone puts you in front of a 30m high wall, tells you to get over it, and then comes back two years later and you're still there, you've made no progress. You should find another wall.

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.

When you’re training Parkour with passion, if you’re good, people will notice you. Don’t go around saying, ‘Hey look at this new move I got.’ No. We used to say, ‘If it’s good we’ll tell you.’ Do it for yourself first.

Bare feet are the best shoes!

First, do it. Second, do it well. Third, do it well and fast — that means you're a professional.
