The ping of a mail loves a reaction. Don't: stop and think. An e-mail is rarely an initiation; it's so often a reaction. It's rarely strategic, so often tactical. It's rarely a wellness strategy, just grumbles about the sticking plaster peeling off under heavy use.
Dig deeper. Initiate and sort it for the long term. It builds a better business, reduces your stress and you'll see your young kids more often.
