I learned in high school that doing everything at the last minute stresses me out and I did a shittier job. I forced myself to finish projects early, I’d have more time to polish them before they were due, I felt good about myself and way less anxious.

Once you have a deadline for a project/assignment etc just act like that deadline is a week earlier. Obviously only works for “big” projects that you know of in advance but those are often a huge source of stress.

Honestly the glamorization of procrastination/slackerism vs being methodical and organized in a boring way has probably needlessly stressed out a lot of people.
