I have touched on the topic of self-management, but, as yet, I have not presented a concise summary of how to go about it.

I am about to remove that shortcoming.

Here are some suggestions on how to go about obtaining the benefits of Self-Management:

• Have a definite purpose - also known as a life purpose.  People who have a definite purpose have an easier time with self-discipline. The reality is - most people, perhaps as many as 98-out-of-100 people, do not have a life purpose. Put another way, most people do not have a consuming, driving, life-long ambition/goal. The natural next question is, can you develop one? The good-news answer to that question is - Yes. [It will take a concerted & lengthy introspection...but, it can be done.]
• "Know Thyself". Perhaps Socrates said this first? Anyhow, it is ancient wisdom which spans many cultures and at least 2 millennia. Again, most people do not have a detailed knowledge of 'self'. That's because they have not taken the time to regularly perform concerted & lengthy introspection. The good news is - many self-development gurus provide help at a cheap price. For example, check out Napoleon Hill's 'Think And Grow Rich'. In that classic, Hill provides a list of questions for an annual self-assessment.
• Understand your personal Values, your personal Rules, and your Habits. And, work at trying New Things which you think may, with your continued effort, become Good Habits.
• Write our Your Vision and Your Goals...and update them at least once a year. Many self-help experts and many psychologists state this is a major key to success. Rather than argue whether or not that can be proved...I suggest you just do it. Really, it does not take much time so why not take a leap of faith and accept it as a good piece of advice.
• Each morning, write out a TO DO list for the day. Make a practice of receiving the merits of The 80/20 Rule, also known as the Pareto Principle: 80% of results are due to 20% of causes. So, focus on the 20% of Actions that generate 80% of the desired results.
