That bad work you did.
You remember it.
That piece of crap you would never put in your portfolio.
Because it is nowhere near your usual standard.
And because it is unlikely to have any positive effect for those that bought it.
Why did you do it?
How did you allow that to happen?
What went wrong?
There will be a whole host of reasons in your head.
As your subconscious ponders the answers.
But there is only one legitimate response in my opinion.
Assuming you are good at what you do.
And assuming you do actually have the ability to recognise and do great work.
It’s because you didn’t say no.
