Personal Development
No matter where people are in life, there is always room for improvement. There are many categories for improving one's life. Whether it be organization, time management, or reading inspirational books and magazines. Many authors have written extensively about these topics and many products have been developed to improve your life.
One of my favorite gurus on the subject of personal effectiveness and personal development is Dr. Stephen Covey, the author of The Seven Habits of Highly Effective People. Dr. Covey has distiguished between managing time and managing ourselves. Dr. Covey has come with a planner system that revolves around principle centered leadership. This system is part of the Franklin Covey Portfolio.
Another popular author on the subjects of personal effectiveness is Brian Tracy.
