Like a wave, nothing can last forever.
Eventually you'll fall out of love. You'll hate what you do in life. You'll have regrets. We hate thinking something will be forever.
That life will become predictable.
It's like when we think of immortality. People wish for it because they are in love with the idea of forever. Living in a moment you cherish, constantly reliving those emotions.
But forever is a scary reality.
Because if we really think about it, forever is an eternity. It's never ending. The same thing, over and over again, but in different time periods with different kinds of people.
So, would you really want forever?
