How to be happy?

Voices in my head

keep telling me,

you did that wrong,

you said that badly,

you’re not good enough,

you should improve,

you shouldn’t have,

you fucked it up again. 

Why don’t they say,

you did that right

you said that well,

you ARE good enough,

you could do worse.

Yes you shall.

Yes you can.
You were brilliant again?
