Holy shit you seem to be talking from my experience!
I have this goddamn client I am firing this month because of that head. Reacts emotionally to every anomaly or disconnect as if the world will fall apart if perfection is not achieve. Majoring on the miners, swearing and bullying, threatening to change terms of our deal. Fuckin stress I don't need for the money.
Weight will be lifted from my shoulders in 2 long weeks and I have already replaced him with a better client.
Best communicated as a reply rather than a post on its own as I like to stay positive in my blog posts. ;)
If something is negative, don't go as often and don't stay as long; and if you avoid going altogether, do that.
It's a good way to live life and I hold to it.
Well done on firing the client, aive done also, it allows more space (energy) to dedicate to the ones you want to work with.
