I definitely feel pressure — my first instinct under it is to try to do everything at once, which I've learned is exactly the instinct to override. So I have a simple system: when the stress spikes, I stop and write down everything on my plate, order it by what's actually due and what actually matters, and then work the list one item at a time. The writing-down step sounds trivial, but it converts a cloud of anxiety into a sequence of tasks.
The week it proved itself: during finals in my senior year, my internship supervisor asked for a project deliverable three days early, colliding with two exams. Old me would have pulled two all-nighters and done everything badly. Instead I listed it all, saw the real conflict was only one afternoon, and asked my supervisor whether a draft Thursday and final Friday would work. It did — she later said she appreciated that I flagged it immediately instead of going quiet and missing the deadline.
That's the other half of my system: when the math genuinely doesn't work, I say so early, while there are still options.
