“you only know yourself when you go beyond your limits”

“If you always put limits on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.”

“you reach your limit, when you give yourself a limit.”

“Have more humility. Remember you don't know the limits of your own abilities. Successful or not, if you keep pushing beyond yourself, you will enrich your own life – and maybe even please a few strangers.”

“Doing risk sport had taught me another important lesson: never exceed your limits. You push the envelope and you live for those moments when you’re right on the edge, but you don’t go over. You have to be true to yourself; you have to know your strengths and limitations and live within your means.”

“There's no limit to how much you'll know, depending how far beyond zebra you go.”
