It's not always a bad plan. If you're taking a test, time is winding down, you've already tried every approach you can think of and there's no greater penalty for a wrong answer than an incomplete one, then guess!
Otherwise, let's begin to channel our enthusiasm and willingness to speak up into referring to our notes so we can follow tested steps, ensuring that at least our attempts are rooted in a rational, recorded framework.
With this spirit our mistakes will be more meaningful; the effort summons actual learning while a corrected guess does generally not, unless a notes and follow steps cycle is completed at the time.
Guessing feels good: easy-peasy! But it's a last-resort for only limited circumstances. At least when we're talking about summoning and working with facts.
That freedom of the wild guess? Go to creativity for that. You can create anything. Of course, now you're responsible for bringing the creation into being.
Takeaways? Play your guesses carefully.
