The roots of education are bitter, but the fruit is sweet.

It is during our darkest moments that we must focus to see the light.

Happiness depends upon ourselves.

Educating the mind without educating the heart is no education at all.

Adventure is worthwhile.

Patience is bitter, but its fruit is sweet.

Love is composed of a single soul inhabiting two bodies.

Education is an ornament in prosperity and a refuge in adversity.

Be a free thinker and don't accept everything you hear as truth. Be critical and evaluate what you believe in.

Knowing yourself is the beginning of all wisdom.

Criticism is something we can avoid easily by saying nothing, doing nothing, and being nothing.

Write as the wind blows and command all words like an army!

The harder you work the luckier you get.

I don't know how many millions of photographs have been taken of me.

When the soul drifts uncertainly between life and the dream, between the mind's disorder and the return to cool reflection, it is in religious thought that we should seek consolation.

When I was working on the lyrics, I thought of all the lullabies we learn as children: "Away in the Manger," William Blake's lullabies. I realized that the key to lullabies is simplicity.

Now I'm starting, relatively, to think straight again. I live one day at a time, one hour at a time. What makes it all worthwhile is my children.

If I can make one generalised statement, and generalised statements are never entirely true, nobody wants to be talked down to, kids included.

True love always happens in a flash.

Everyone has something to sell. The greatest thing you can ever sell is an idea or talent.

There is no bigger waste of time than doing 90% of what is necessary.
