Yep, it's time for you to find a new comfort zone. And maybe something you do that your sister doesn't, so that's one area you can have all to yourself. Academic work isn't everything, especially since that old adage is true: there's a big difference between book smarts and street smarts. And look at you, getting your head screwed on straight so much sooner than she is! You're gonna be over and done with the eye-opening epiphanies and the family-style throw-downs while she's still waiting to get a pat on the head and a gold star.

An old proverb says "The best techniques are passed on by the survivors." In other words, anybody can do anything for a certain amount of time. Whether you are successful enough to do it again later (or be asked to do it again later) is what determines how good at it you are. So your sister's an academic, whoop-de-doo. Now, can she make a living with her academics or does she actually know how to do other shit that'll put bread on the table and keep wattage (or is the proper term volts or amps or currents?) flowing into the computer?
