People are very bad at evaluating opportunity cost, in general. In both directions. They’ll do stuff that has way too high of an opportunity cost, and they won’t do stuff when the opportunity cost is practically zero.
Someone may say to you, “Hey, want to go do this weird thing with me today?” The wrong question to ask yourself is “Do I want to do this thing?” The correct questions is: “Do I have anything better to do?”
You probably don’t! So go do the thing. There’s a lot of potential upside and very little to lose.
