Free Time is not free. Especially if you have something to do, such as a project, homework or a presentation to prepare for. When you think about using your free time for family or relaxing. Then it is no longer free time. Your spending it to help prepare yourself for your tasks that require more energy or to recover your body from the task. When you use it for you family, you are building a relationship and giving them your attention. So free time is never actually free, your using it one way or another for something you care about. So use your time wisely.
Self discipline means to teach. Teaching ourselves is really about making choices, making change, employing your willpower, and taking responsibility. You need to empower yourself to get things done.
Procrastination is when you care but you don't know why you care. This is usually because we don't have all the information we need to get something done. When you are procrastinating something, ask yourself, do I understand the task?
Laziness is when we don't care and we know why we don't care.
