There is no reason to be unhappy.
If I am out of sorts, I say to God, 'How can I serve You?' and then get on with it.
The unhappiness always passes.
Under no circumstances is it useful to talk extensively about myself except to admit my character defects and poor behaviour ('twists of character'; 'dark crannies').
That should take about five minutes.
Maybe another five minutes planning the Next Right Thing.
But then ... the quarantining of self.
At first, one is taking the right action unhappily.
But eventually one gets so involved in and excited by carrying the message and Doing Good Helping one quite forgets to be unhappy.
If I'm remaining unhappy today, I'm choosing it.
