It is true that too much belief can be bad for your health.

The truth is that relative income is not directly related to happiness. Nonpartisan social-survey data clearly show that the big driver of happiness is earned success: a person's belief that he has created value in his life or the life of others.

America has believed that in differentiation not in uniformity lies the path of progress. It acted on this belief it has advanced human happiness and it has prospered.

There are many qualities that make a great leader. But having strong beliefs being able to stick with them through popular and unpopular times is the most important characteristic of a great leader.

No sadder proof can be given by a man of his own littleness than disbelief in great men.

No man is great enough or wise enough for any of us to surrender our destiny to. The only way in which anyone can lead us is to restore to us the belief in our own guidance.

A lot of companies have chosen to downsize and maybe that was the right thing for them. We chose a different path. Our belief was that if we kept putting great products in front of customers they would continue to open their wallets.

What we have to do is strike a balance between the idea that government should do everything and the idea the belief that government ought to do nothing. Strike a balance.

President Obama's call for nearly a half-trillion dollars in more government stimulus when America has more than $14 trillion in debt is guided by his mistaken belief that we can spend our way to prosperity.

And I don't think that government has a role in telling people how to live their lives. Maybe a minister does maybe your belief in God does maybe there's another set of moral codes but I don't think government has a role.
