A good habit takes months or even years to develop. But it takes less than a week to build bad habits. And once they form, they work as an invisible force to weaken your thoughts and kill you from inside. They keep you dull, negative, unproductive and stressed. It can lead to depression, headaches, and other mental disabilities. Well, no one is perfect! We all have some positive and negative. But no one knows the real devil inside you. And the only thing you can do is to look inside in you and compare your habits with these bad habits on the list. And if any of these habits reside in you, you need to quit these right away. original source - https://beginnersblog.org/bad-habits/
