We can’t expect the impossible.
There are many things which aren’t ours to want.
Things which aren’t within our control. Things which are going to happen regardless.
All we can do is develop the right opinion of them. We can cultivate the correct attitude towards them, practicing the appropriate reaction.
Accept that they can happen, that they will happen.
Then, when they do happen, we won’t be surprised.
We will just respond accordingly.
We can’t predict the future. But we can be prepared for what it might hold.
