1. Always be optimistic: Only by maintaining an optimistic attitude can we achieve the impossible and feel happy.

Second, do something that makes you feel uncomfortable: leave your comfort zone and achieve your small goals. When you achieve these goals, you will experience a kind of happiness that you have never experienced before. This kind of happiness is impossible for anyone to bring you.

Third, give up if you can't change others: people who try to change others will basically fail. Only with tolerance, understanding and the idea of seeking common ground while reserving differences can we be happy with each other.

Fourth, reduce desire: when a person's ability is lower than desire, we will feel pain, often depression and sigh. Of course, I won't feel happy.
