let them all in or only allow for some specific apps (if so which ones)?
It’s all personal preference but I’d go crazy if I had email notifications on. If it’s urgent and I want you to have instant access to me you should be able to text me. Otherwise, email is something I look at at beginning or end of day. Same for work. It’s well documented at this point how destructive interruptions and distractions are to reaching deeper levels of thought, engagement and productivity…and that is not restricted to the work world.
