Having high expectations about the past is a one-way street to unhappiness.
The past is fixed.
There is nothing that can be done when the head is cut off, except to bury the body. Leaving the body out in the open will only lead to swelling and decay.
Having high expectations about the present is delusional. It is what it is, yet it keeps going.
The present is fluid.
The air that you breathe is the air that is available to you, not the one you wish was available to you. If you stop breathing until you get your preferrred air, you will die needlessly.
Having high expectations about the future is fit for purpose. Expectations are designed to model what you want from what has not yet come.
The future is illusionary.
Given the choice between feeling upbeat or feeling downcast about the future, it is wiser to be upbeat, as there is no favourable reason to suffer for what is illusionary.
