If you could exchange one relatively mundane requirement with another of about equal semi-objective difficulty but which you're better at fulfilling, what would the switch be?

For example, instead of taking tests to pass a Statistics course, you have to knit a sweater. Instead of dealing with your finances, you have to juggle odd-shaped objects for half an hour. Instead of going to work, you have to run fifty miles. Instead of worrying about whether you'll get the job, you have to defeat fifteen martial artists in sparring atop uneven poles. Whatever.
