Clients who breath down your neck

Do y'all feel significantly less inclined to give good work when you're being hounded by clients?

For instance, I did a music video for cheap (500€) and the guy expected it to be done in a day or two and he even went as far as saying "all sorts of people will be done with the video In a day or two". That's strike one for me.

I told him the video will be done in a week or two, not next day or 2 days.

During next few days, I finished the first draft for review and approval.

He asked for a few changes, which I did in a few days, and he's starting to hound me.

I didn't appreciate the fact I got the first edit done fast, and he asked for revisions, and is now breathing down my neck that I'm taking too much time to do the revisions. there's strike 2 for me

So I send the 2nd draft, and he asked for more revisions. so I start working on them, and he messages me that he's not happy with how long it's taking which is strike 3 considering this is his second revision and he's pissed it's taking time.

It's been like 3 or 4 weeks now, I've sent the final and I could care less what he thinks of it or if he even releases the music video.
