In life, everything is constantly moving and changing, in fact I can't think of one single thing that ever stays the same in any way. Even after death, the body rots away, giving way for more life in one form or another.
Even us ourselves are constantly changing both mentally and physically. I am different now to how I was a moment ago. I have just experienced more life and been part of that change through and through. We are intricately connected to every change that happens on earth, largely through the unconscious, but partly through the conscious. When conscious we have the power to change or influence certain changes, but through the unconscious we cannot choose. These things will happen anyway, as they are created and influenced by "other people's choices".
We build up a need like an addiction throughout life to want certain things, whether it be wanting the good things to stay, or the bad things to go, we always want it to go our way. If one thing is certain, it is that things won't always go our way. This building up of wants, we call hope.
Hope, is a dangerous thing. It almost always leads to mental pain and anguish when things don't go the way we hope. So why do it in the first place?
At any moment in time, everyone has everything they need to exist(if they didn't, they wouldn't be here - then it wouldn't matter anyway). Everything else is extra, and for that we should be happy.
Everything changes, that is what life is - trying to go against it is agains the very nature of what life is, hence the pain it causes.
