Life requires precipitation and enough time to reflect, in order to make yourself more perfect and outstanding. Life requires accumulation, and only by looking back often can we sublimate in the taste of gains and losses, sweetness and bitterness. Looking back often is easier said than done. Life is inert, and life is often lost. You will complain about God's injustice, you will lament the fate of your fate; you will resent the leader's lack of discernment, and you will regret that your friends betrayed you for no reason; you can rebuke others' shortcomings, and you can reflect on your own shortcomings... So, in life Looking back, it takes a certain amount of sincerity and broadmindedness, as well as a certain amount of perseverance and resilience.

Look back often!

Looking back, there is the clear sky behind you.

Looking back, behind you are the philosophies of those wise men.

Looking back, the road ahead is also written behind you.
