Along with expecting the worse [ or being prepare for it ] and being pleasantly surprised when it does not blow up in your face, I also believe there is a reason for everything. Sounds cliche, but I keep this caveat always in my mind.
While things happen for a reason all too often, we do not need to know the reason, or it is not time for the reason to be divulged yet. IME too many people struggle and 'punish' themselves for not knowing what the reason is.
Acceptance is the key.
You know it is what is unless you can do something to change it..
Change is very hard for many and most possess a little bit inside them that wants to resist change.
