There is another version of me who decides that physics is hard, as are yoga and baking, and instead spends her free time browsing social media.
There's a scientific name for Version 1, and it's not "you've gotta be kidding me." Instead, it's the "anticipating self." Version 2, on the other hand, is the "experiencing self." And here's the kicker: With a shift in mindset, it's possible to replace Version 2 with the ever-virtuous Version 1.
That's according to Laura Vanderkam, a time-management expert and the author of "Off the Clock: How to Feel Less Busy While Getting More Done." Vanderkam argues that there are three selves to every individual: anticipating, experiencing, and remembering.
The key to managing your time well (i.e. actually reading those physics books) is to ask yourself: Did my anticipating self want to do this? If so, do it! Your remembering self will be glad to have done it — and remembering lasts a whole lot longer than experiencing.
Vanderkam's anticipating/experiencing/remembering framework is an extension of an argument made by Nobel Prize-winning psychologist (and pioneering behavioral economist) Daniel Kahneman. Kahneman argues that everyone is made up of two selves: experiencing, who lives in the moment, and remembering, who lives in the past.
Vanderkam goes so far as to suggest that our remembering self is "the keeper of our identity." The problem, she writes, is that "the present — the moment occupied by the experiencing self — has a disproportionate effect on our actions, given its fleeting nature."
Sure, it feels good in the moment to scroll mindlessly through pretty pictures of friends' beach vacations. But when you look back, you'll remember that day as much the same as every other lazy day — in fact, you might not even remember it at all.
The goal, then, is not to live in the present, or like there's no tomorrow, as so many pop songs would have us do. It's to live for tomorrow, and for the years after that, when you'll turn back to your memories as an indicator of what your life was like: happy and fulfilling or unsatisfying and boring.
To be sure, this mindset shift takes some effort, specifically resisting the experiencing self's inertia. It might take a few tries before it kicks in, but at some point you'll realise that the anticipating self, in cahoots with your remembering self, does indeed have your best interests in mind.
