Pay no mind to those who talk behind your back, it simply means that you are two steps ahead.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

The strong man is the one who is able to intercept at will the communication between the senses and the mind.

Troubles are only mental; it is the mind that manufactures them, and the mind can gorge them, banish them, abolish them.

I will not let anyone walk through my mind with their dirty feet.

Once you have made up your mind, stick to it; there no longer any 'if' or 'but'.
