Only when our clever brain and our human heart work together in harmony can we achieve our true potential.

Reach for it, you know. Go push yourself as far as you can.

Happiness comes to those who deliberately expand their horizons and experiences.

Growth comes at the point of resistance. We learn by pushing ourselves and finding what really lies at the outer reaches of our abilities.

La única posibilidad de descubrir los límites de lo posible es aventurarse un poco más allá de ellos, hacia lo imposible.

Once we accept our limits, we go beyond them.

It is by fighting the limitations, temptations, and failures of the world that we reach our highest possibilities.

We are at our very best, and we are happiest, when we are fully engaged in work we enjoy on the journey toward the goal we've established for ourselves.

In each of us are places where we have never gone. Only by pressing the limits do you ever find them.

Life achieves its summit when it does to the uttermost that which it was equipped to do.

The limits of possible can only be defined by going beyond them into the impossible.

Happiness is the reward we get for living to the highest right we know.

But every person must have the desire to push oneself to the limit!

True happiness occurs only when you find the problems you enjoy having and enjoy solving.
