If you know how some habits affect others, you can learn how to effectively manage them.
Harmful habits like gluttony have the opposite effect. Once you enjoy a lot of food, but soon begins to lack energy for work and hobbies, you become slower.
The habit can be called important for two reasons:
1 . What it gives you, makes your life better - then you continue to do what you like.
2. Its consequences make your life worse - then you have a desire to get rid of it.
Pay attention, how much worse you feel when you surrender to a bad habit, and how much more energetic you become when you give preference to something useful. So your life will become more conscious.
