Notes to myself

Twice in the past two days, I've lost my temper with people who've asked me to make my mind up between two alternatives 'and then just be happy'.

Here's what I don't understand: Why is it so hard to comprehend that both alternatives may be equally desirable, both may be impossible, and therefore my final decision will always involve a little ambivalence?

Surely accepting that is the first step to choosing either way?
