Yet that insidious voice keeps whispering. “But this is an opportunity, man! You gotta network. Get out there! Everybody promotes their stuff. Be a pro. Seize the moment, dude!”~ Steven Pressfield from, https://stevenpressfield.com/2013/01/opportunities-are-bullshit/
One way to look at it is through the prism of money. If someone wants you to do something and the remuneration is “exposure” or “opportunity” … you have answered your own question.
It’s important to learn to avoid the siren-call of such “opportunities.” I’m scare-quoting because, as Pressfield points out, they’re not actually opportunities. They are in fact a siren-call attempting to lure your ship onto the rocks. They’re a siren call because the message is exactly what you want to hear: “Your work is good. Your work is valuable. We want you to succeed.”
Actual opportunity sounds different. The message is just off to the side from what you wanted to hear: “What you’re doing is interesting. It makes me think of this thing I’m doing over here. It occurs to me that we might work together on it.” You’re left thinking about some interesting tangential idea. Instead of thinking, (as with the siren-call,) “is this going to be worth it,” you’re thinking, “that’s interesting, I’d like to be involved in that.” Certainly, true opportunities may come with money, but in your own thinking that’s an interesting nice-to-have; but it’s secondary. Take opportunities where the opportunity itself interests you. Don’t take “opportunities” where the potential, down-the-road benefit interests you.
