Like is a duration between birth and death. The Painful moment which tends to make life amazing is struggle. Hence, like and struggle are two part of same coin. one is incomplete with the absence of other.

Though life and struggle are interconnected with each other but it is not universal. You can see a man who is enjoying his beautiful life doing nothing. In the same fashion, you can see man doing hardwork from dawn to dusk to just to join hand to mouth. But keep in mind that in every person's like there is always Someone who is struggling for him. That's why we can say

"Enjoy is for alone But struggle is for all"
