You never know what motivates you.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
The secret of getting ahead is getting started.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
If you can dream it, you can do it.
Never complain and never explain.
The wise does at once what the fool does at last.
Problems are not stop signs, they are guidelines.
How many of you have broken no laws this month? That's the kind of society I want to build. I want a guarantee - with physics and mathematics, not with laws - that we can give ourselves real privacy of personal communications.
