Of all the creatures of earth, only human beings can change their patterns. Man alone is the architect of his destiny. Human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives.

The unrest which keeps the never-stopping clock metaphysics going is the thought that the non-existence of this world is just as possible as its existence.

A little cooling down of animal excitability and instinct, a little loss of animal toughness, a little irritable weakness and descent of the pain-threshold, will bring the worm at the core of all our usual springs of delight into full view, and turn us into melancholy meta physicians.

Metaphysics means nothing but an unusually obstinate effort to think clearly.

The greatest weapon against stress is our ability to choose one thought over another.

It is our attitude at the beginning of a difficult undertaking which, more than anything else, will determine its successful outcome.

We don't laugh because we're happy -- we're happy because we laugh

When you have to make a choice and don't make it, that is in itself a choice.

I don't sing because I'm happy; I'm happy because I sing.

Man can alter his life by altering his thinking.

If you care enough for a result, you will most certainly attain it.

Faith means belief in something concerning which doubt is theoretically possible

Whenever you're in conflict with someone, there is one factor that can make the difference between damaging your relationship and deepening it. That factor is attitude.

Seek out that particular mental attribute which makes you feel most deeply and vitally alive, along with which comes the inner voice which says, "This is the real me," and when you have found that attitude, follow it.
