Every day, there are a variety of sounds around us: the children’s laughter, the birds of the tweet, and friends to chat, or radio to play the beautiful songs – which makes our lives become richer.

When we have normal hearing, we live a carefree life. It allows us to participate in social activities, work and communicate with people. It allows us to maintain close contact with the outside world, but also in potentially dangerous circumstances will remind us to ensure our safety. There are a lot of voices in life that we need to hear, such as the ringing of the phone, the cry of the baby, the ringing of the fire, which is just a few of them.

There are a lot of new and interesting things in our life, but how we are going to pay attention to them, which is not actually determined by our brains. Everyone has different preferences and different hobbies, these hobbies will bring us the feeling of happiness, chasing happiness is human nature. So we will focus on interested things and voices, while giving more attention to the need for human beings to get more happiness and give more attention to the so-called depth of attention, focus on one thing or something The In fact, we have no way to give more attention to the happy things. So when we can not get happy, we will take the initiative to find happiness, a wide range of attention to pay attention to more things, which is breadth of attention. Nature is inevitable, as a child, they are still learning, understanding, curious is the child’s nature.
