Brighter Side?

A thought comes,
It makes a fog,
And a mist to match,
In your clear mind.

All things seem useless,
All thoughts baseless,
And all ideas worthless,
In your now foggy mind.

You’re pessimistic, they say,
Look at the brighter side,
Life is not always a rough road,
It’s got a bright side to it.

I do say, verily,
Optimism or pessimism,
Are just big words,
For life, surely, is your own doing.
