The measure of intelligence is the ability to change.
You are never too old to set another goal or to dream a new dream.
Our lives begin to end the day we become silent about things that matter.
It does not matter how slowly you go as long as you do not stop.
In three words I can sum up everything I've learned about life: it goes on.
The only thing worse than being blind is having sight but no vision.
Change your life today. Don't gamble on the future, act now, without delay.
Life is what happens when you're busy making other plans.
The future belongs to those who believe in the beauty of their dreams.
Don't watch the clock; do what it does. Keep going.
The best way to predict the future is to invent it.
The only limit to our realization of tomorrow will be our doubts of today.
The only true wisdom is in knowing you know nothing.
