Thinking about life a lot lately. Some of the best decisions I've made are stepping away from things that aren't for me anymore. I was an MBA student for a whole 2 weeks before learning the sunk cost fallacy. There & then, I realized 2 weeks shouldn't decide the next 3 years. (1/

In a nutshell, sunk costs are sacrifices & costs already made & spent. The fallacy then shows up when we take these sunk costs into account & consideration when making future decisions. Where in fact, we should be making decisions based on what's best NOW & ahead. (2/

Often, we're a bit blinded by the investment we've already made be it emotional, mental, physical, spiritual. "We've already put this much into A, so we might as well continue putting more into A rather than changing to B." (3/)

The part that sticks with me about this is that if we continue choosing & investing in A, we deny choosing & investing in B (even if it's better) simply because it didn't come first chronologically. It requires an uncomfortable change of course to let go of A & go for B. (4/)

We give into this fallacy all the time in jobs, in relationships, in routines, in habits, in small & big life decisions. We assume what we have already put in is enough to keep us in. We overvalue what we've spent & find it hard to admit when we weren't first right. (5/)

I don't have a point to this thread other to encourage everyone to think about the times we can complacently accept what we actually can change because it's an easier or more comfortable A compared to a more challenging & course changing B. (6/)
