Fear is caused by the uncertainty of the future. Sorrow is caused by the remembrance of the past. Try to keep your thoughts in the present, for the future we will never know and the past we may never understand.
Any sufficiently advanced technology is indistinguishable from magic.
The future has several names. For the weak, it is the impossible. For the fainthearted, it is the unknown. For the thoughtful and valiant, it is the ideal.
Don't worry about what anybody else is going to do. The best way to predict the future is to invent it.
The best thing about the future is that it comes one day at a time.
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.
Stay away from what might have been and look at what will be.
Dear future generations: Please accept our apologies. We were rolling drunk on petroleum. Love, 2006 A.D.
Gosh, life is so cruel. It shows you happiness, then whisks it all away, and you're left with nothing but memories and broken promises about a future you'd do anything to have.
If you love me, let me know. If not, please, gently let me go.
