The greatest results in life are usually attained by simple means and the exercise of ordinary qualities. These may for the most part be summed in these two: common-sense and perseverance.

If you wish success in life, make perseverance your bosom friend, experience your wise counselor,
caution your elder brother, and hope your guardian genius.

Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

The difference between a successful person and others is not a lack of strength, not a lack of knowledge,
but rather a lack in will.

The important thing in life is to have great aim and to possess the aptitude and the perseverance to attain it.

Success in life is a matter not so much of talent or opportunity as of concentration and perseverance.

It is interesting to notice how some minds seem almost to create themselves, springing up under every disadvantage, and working their solitary but irresistible way through a thousand obstacles.

It does not matter how slowly you go so long as you do not stop.
