A mate of mine shared a while back:
I do have tired days where I'm like “Ah, it’s probably ok, I don’t have the energy to test this, I’ll let the client do it, they’ll review it anyway”. Not great, but I do have those days ¯\_(ツ)_/¯
I get it. I've done this plenty of times. No judgment here. At least he's honest about it! The urge is strong.
You see, despite my protestations otherwise, I do have an ego.
It's not a desirable thing and I'm doing all I can to leave it behind... but it's there.
Sometimes the narrative goes:
"I built it. It'll be right."
It ain't fine. It ain't good.
Your client isn't sitting there thinking "oh this is fun". Especially when they can't test the course because they are stuck due to something silly.
A few years back, I sent a course to a client who wasn't able to progress past the first slide (due to a transparent image background blocking the button). I could have played the whole "Have you tried clearing your cache?" game while I quickly republished it, but where's the fun in that?
Instead, we had a conversation about testing fatigue and the impact of endless minor changes on the quality of the final output. And once we had a clear understanding of what the issues really were, we could fix them.
