Weak men wait for opportunities; strong men make them.

The first part of success is 'Get-to-it-iveness'; the second part of success is 'Stick-to-it-iveness'.

When a man feels throbbing within him the power to do what he undertakes as well as it can possibly be done, this is happiness, this is success.

Be larger than your task.

The wearer of smiles and the bearer of a kindly disposition needs no introduction, but is welcome anywhere.

To think you can creates the force that can.

You will find the whole world will change to you when you change your attitude toward it.
