Garner up pleasant thoughts in your mind, for pleasant thoughts make pleasant lives.

The only means of strengthening one's intellect is to make up one's mind about nothing, to let the mind be a thoroughfare for all thoughts.

Once I make up my mind, I'm full of indecision.

Your future is only as bright as your mind is open.

Make up your mind to act decidedly and take the consequences. No good is ever done in this world by hesitation.

To make pleasures pleasant shortens them.
