I have not failed. I've just found 10,000 ways that won't work.
It does not matter how slowly you go as long as you do not stop.

The only way to do great work is to love what you do.
In the end, it's not the years in your life that count. It's the life in your years.
The way to get started is to quit talking and begin doing.

In three words I can sum up everything I've learned about life: it goes on.
It's not what you look at that matters, it's what you see.
Life is what happens when you're busy making other plans.
The best way to predict the future is to invent it.
The future belongs to those who believe in the beauty of their dreams.
The only true wisdom is in knowing you know nothing.

The only limit to our realization of tomorrow will be our doubts of today.
The only person you are destined to become is the person you decide to be.
