It always seems impossible until it's done.
The best way to predict the future is to invent it.
Do not wait to strike till the iron is hot, but make it hot by striking.
The best preparation for tomorrow is doing your best today.
The future starts today, not tomorrow.
The future belongs to those who believe in the beauty of their dreams.
The only limit to our realization of tomorrow will be our doubts of today.
The only way to do great work is to love what you do.
Your time is limited, don't waste it living someone else's life.
Success is not final, failure is not fatal: It is the courage to continue that counts.
