A trick to think like a Radagast: try to see not what is but what could be.
What is is often a bit of a bummer; imperfect, messy, busted.
But what could be is more inspiring, the sky's the limit.
If you look at a thing that someone has and help them see what it could be, it can inspire them, fire them up, make them feel engaged and seen.
Instead of saying "here's why what you've got has problems to address" say "here's why the thing you're holding could be great, if only you were to…"
You get people to believe in themselves, and to dream big and be engaged in writing their own story.
Everybody wins.
