Life is like riding a bicycle.
In order to keep your balance, you must keep moving.

Creativity is intelligence having fun.

Logic will get you from A to B.
Imagination will take you everywhere.

I am thankful to all those who said NO to me.
It’s because of them I did it myself.

If A is a success in life, then A equals X plus Y plus Z.

Work is X.
Y is play.
and Z is keeping your mouth shut.

It is strange to be known so universally and yet to be so lonely.

Everything should be made as simple as possible,
but not simpler.

No, this trick won’t work…
How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?
