Poooooof...

A thought occurs.

Good, bad, or ugly. Doesn’t matter.

Noble, pervert, or hideous. Doesn’t matter.

It has ALREADY occurred.

Neither can YOU change that, or can you influence THAT, and nor can you witness that.

Poof… it’s gone.

These stream of poofs is what your story is made up of.

Selfishness

Utmost degree of selfishness will not have any expectations from anyone. All my disappointments have stemmed from one or other form of expectation.
That means the most selfish being will not have any expectation from 'self' as well :)
What a relief!
