Before speaking of this topic, there is a great funny saying I want to share with you. It says that when a person is starving, he or she only has one problem, but when they are full, they have to face countless annoying things. So, when you ask me something about improving sleep quality, my experience is that you need to empty you mind and not to focus on the things which is eally hard to achieve. Everyone living in this world is one of a kind, but no one is perfect! We tend to compare to others on money, position or reputatio. Once we think that something we owned are shorter than others, a special feeling usually fill up our mind cause us to lose confidence. We would try our best to get all the things we want, but as a consequence, we always fail. We even think that doing chores, taking care of children are wasting time. All the bad thoughts in your mind make your life getting worse until you get insomnic night by night. Everything happened was not occasional, it has its own origin. Only with a positive motive, the thing can go well!
