Whether it's a bizarre chap on Twitter merrily proclaiming that women belong in the kitchen, a prominent academic who wants to ban faith schools... so long as they're not making threats, I really hope we can try to shut them down with our words, reason and logic. Not by calling for their banishment from every which platform - virtual or not.
When you're burned out, you have a voice in your head which will tell you "I just cannot do anymore work." Now we're getting somewhere! At this point you'll examine everything you do to see what can be gotten rid of e.g. low paying clients/unnecessary work/anything else that takes up more time that it should (remember what I said earlier about getting drunk?).
