The key to success is effort. The bigger the goal, the greater the effort.

Success or failure can only be measured in terms of a particular objective. The success of a person whose life objective is money or status will look very different than the success of one who sets out to make a positive difference in the world.

What will matter is not your competence, but your character. What will matter is not how many people you knew but how many will feel a lasting loss when you are gone. What will matter is how long you will be remembered, by who and for what?

A person is said to have good character when their habits, dispositions and conduct reflect a deep commitment to ethical virtues and moral principles.

Whatever you do, make a difference. Earn the right to look back at something and say, 'I did that.'

If you want to be happy, learn to be alone without being lonely. Learn that being alone does not mean being unhappy. The world is full of plenty of interesting and enjoyable things to do and people who can enrich your life.

The best way to show true gratitude for all our blessings is to be genuinely happy.
