[contingencies]

In a vague sense only, and only if strictly necessary - eg. travel, meetings. I actually strongly seek to avoid any fixed time commitments any day of the week, or indeed to have to be aware of what day of the week or month of the year it is, because it create needless overhead through "unflowable time". The critical cause is service providers unavailable 24x7x365 where my preference is uncommon (eg. after waking up early in the morning, it is frequently impossible to swim or eat although I would like to). I avoid alarms. To do lists are a rarity. I try not to block others and prioritize giving them positively framed critical feedback or research output ASAP over my own work.
