"Behind all difficulties is the way you grow. Behind everything, there is a price tag, behind the easy is staying where you are, and behind the difficult is a better self. So, don't be afraid of difficulties, this is to test you, to cross you, and to improve you. A person's life is to "go through a moat, grow a wisdom", and constantly optimize his own process. Human life is a process of continuous cultivation and growth. The most beautiful thing in life is to meet a better and better self. Look at the problem from a different length, and you will gain a tougher and better version of yourself. Look at the problem from a different position, and you will gain a multi-dimensional and richer self. Look at the problem from a different mentality, and you will gain an open-minded and happier self."
