From the book: Lists To Live By
1. Start With Small Things: Learning self-discipline in the little things of life prepare us for big successes. On the other hand, those who are undisciplined in small matters will likely be undisciplined in more important matters.
2. Get Yourself Organized: Make a schedule, however detailed or general you are comfortable with, and stick to it. Have a to-do list of tasks you need to accomplish.
3. Don't Constantly Seek To Be Entertained: When you have free time, do things that are productive instead of merely entertaining. Read a good book, listen to classical music, take a walk, or have a conversation with someone.
4. Be On Time: Being punctual marks a life that is organized. It reveals a person whose desires, activities, and responsibilities are under control, allowing him to get where he needs to be when he needs to be there.
5. Keep Your Word: If you say you're going to do something, do it ---when you said you would do it and how you said you would do it. When you make commitments, see them through. That calls for the discipline to properly evaluate whether you have the time and capability to do something.
6. Do The Most Difficult Tasks First: Most people do just the opposite, spending their time doing the easier, low priority tasks. But when they run out of time (and energy), the difficult, high-priority tasks are left undone.
7. Finish What You Start: If you start something, finish it. Therein lies an important key to developing self-discipline.
8. Accept Correction: Correction helps you develop self-discipline by showing you what you need to avoid. Thus, it should not be rejected but accepted gladly.
9. Practice Self-Denial: Learn to say no to your feelings and impulses. Occasionally deny yourself pleasures that are perfectly legitimate for you to enjoy.
10. Welcome Responsibility: Volunteer to do things that need to be done. That will force you to have your life organized enough to have time for such projects.
