Don’t hold on to someone who’s leaving, otherwise you won’t meet the one who’s coming.
We know what we are, but know not what we may be.
How foolish is man! He ruins the present while worrying about the future, but weeps in the future by recalling his past!
There is nothing more powerful than an idea whose time has come.
Take no thought for tomorrow; for tomorrow shall take thought for the things of itself. Matthew 6:34
The Utopias of one age have been the realities of the next.
You are always free to change your mind and choose a different future, or a different past.
The best way to predict the future is to create it.
It is said that the present is pregnant with the future.
When I was a child, my mother said to me, 'If you become a soldier, you'll be a general. if you become a monk you'll end up as the pope.' Instead I became a painter and wound up as Picasso.
Tomorrow is often the busiest day of the week.
The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be.
When all else is lost, the future still remains.
It is not in the stars to hold our destiny but in ourselves.
Yesterday is but today's memory, and tomorrow is today's dream.
