You will never succeed while smarting under the drudgery of your occupation, if you are constantly haunted with the idea that you could succeed better in something else.

Great tenacity of purpose is the only thing that will carry you over the hard places which appear in every career to ultimate triumph.

This determination, or fixity of purpose, has a great moral bearing upon our success, for it leads others to feel confidence in us, and this is everything.

It gives credit and moral support in a thousand ways.

People always believe in a man with a fixed purpose, and will help him twice as quickly as one who is loosely or indifferently attached to his vocation, and liable at any time to make a change, or to fail.
