This is your ☀️Mental Health Monday☀️ reminder to think about how you think (it’s very meta, I know)!
Sometimes, in an attempt to protect us, our brains lead us astray (Sunk Cost Fallacy, anyone?!).
If you’ve fallen into any of these traps, I’m encouraging you to enact “The Fresh Start Effect” this week to avoid regret in the future 🙌🩷💯

Knowing how your brain fools you is only useful if it changes what you do. A couple of these sting.
Which one are you going to use first?
Roger Buehler, Dale Griffin, and Michael Ross published the study that named the planning fallacy in 1994. They asked psychology students to predict the day they would finish their honors thesis. The average prediction was 33.9 days. The average reality was 55.5 days. The researchers also asked for a worst-case estimate, assuming everything went wrong, and got 48.6 days. Even the doomsday number was optimistic.
