Parkour is really a practice of getting to know yourself, what you're able to do, what are your limits. As you train, you start knowing what you can do.

The better you know yourself, the better your relationship with the rest of the world.

Know yourself to improve yourself.

Meditation is a journey to know yourself. Knowing yourself has many layers. Start knowing your bodily discomforts. Know your success, know your failures. Know your fears. Know your irritations. Know your pleasures, joy and happiness. Know your mental wounds. Go deeper and examine every feeling you have.

Know yourself. Don't accept your dog's admiration as conclusive evidence that you are wonderful.

Trust your gut. You know yourself, so don't let somebody else tell you who you are.
