How likely are you to be stressed in academia?
A majority of the expectations tend to be self-imposed.

While there are some things you're made to do by others, most deadlines etc come from your own choices. Do you agree to referee that paper? Do you want to submit to that conference? Do you agree to give that talk?

There is no &quot;having done enough&quot;.

There is always something more that you could do. There will be almost certainly peers who get much, much more done than you (or at least appear to do). Research is never finished. The academic job market is very tight, so until you have tenure, there is always this question of &quot;could doing this extra thing be the decisive factor in whether or not I get a job&quot;?

Deadlines tend to be on a medium time scale.

Unless you are eg a postdoc with a micromanaging team lead, you will be rather flexible in the short term. Teaching aside, things are of the &quot;do this this week/month&quot;, nor &quot;this day&quot;.

There does seem to be a widespread culture of celebrating stress.

While relaxed academics exist, in my experience most academics tend to convey an aura of constant low-level stress. Of those, many seem to enjoy this. Admitting to be overwhelmed is very much acceptable, but I suspect that the stress can be infectious for some people.
