Successful Remote = Letting Go of Instant Gratification
Possibly one of the hardest things that people need to let go of in a remote environment is the need for 'instant gratification'.
If you're defaulting to trusting that your people will 'get it done' whilst also having autonomy and power over their day and time, then you need to let go of the pull towards 'instant responses' and 'instant feedback'.
Without a doubt, there needs to be an emergency button / red-phone of sorts for those instances where urgent intervention or feedback is needed. But the number of instances that really, truly, absolutely need instant answers is almost certainly going to be a lot fewer than you think.
