“Is this on my ‘to-don’t’ list?”
Even worse than taking on work that might not fit with your overall mission is work that you pointedly told yourself you wouldn’t get sucked into, but find yourself getting sucked into.
We don’t always take on such work wittingly, we can forget in the flurry and agree to it while forgetting how disagreeable the task is.
Be cognizant of what work simply must not end up on your plate and why.
