Answer:
Life is short, so it's important to enjoy it as much as possible.
Step-by-step explanation:
In the poem "Loveliest of Trees' by Alfred Edward Housman, the poem deals with the passing of time and how fast it goes. So it is upon man to try to enjoy as much as possible, for those days gone by will never come back again.
The poem talks of how time goes too fast, how a man's life is getting shorter day by day. The fleeting nature of time makes it upon man to enjoy as much as he can, taking up every opportunity to see and feel things. Moments gone by will no longer come back, it is an irreversible process. Once gone, it is forever gone. By referring to the blossoming of the cherry trees, he is indirectly suggesting that one must make time to enjoy the blossoms, for they will be gone in no time and there won't be any coming back. This is another way of implying the importance of enjoying life's present moments for they will soon be gone.
