Difficulties come not to obstruct, but to instruct.

The more you discipline yourself to persist on a major task, the more you like and respect yourself, and the higher is your self-esteem.

Discipline is what you must have to resist the lure of excuses

The future belongs to the competent. It belongs to those who are very, very good at what they do. It does not belong to the well meaning.

Every study of high achieving men and women proves that greatness in life is only possible when you become outstanding at your chosen field.

The more you discipline yourself to use your time well, the happier you will feel and the better will be the quality of your life in every area.
