Life always offers you a second change. It's called tomorrow

You can't start next chapter of your life if you keep re-reading the last one

Success is the ability to go from one failure to another with no loss of enthusiasm.

It’s how you deal with failure that determines how you achieve success.

Only the people who dare to fail, will achieve big success.

Don’t be discouraged. It’s often the last key in the bunch that opens the lock.

The winner says, “It may be difficult but it is possible”. The loser says, “It may be possible but it is too difficult”.

All glory comes from daring to begin.

The poorest of all people is not the person without a cent, but the person without a dream.

Happiness is when what you think, what you say, and what you do are in harmony.

Wear a smile and have friends; wear a scowl and have wrinkles.

Strive not to be a success, but rather to be of value.

Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

Life is a tragedy when seen in close-up, but a comedy in long-shot.
