But I've had several workshop experiences that were just hellishly bad. If you can find the right workshop, with the right people, it can be bliss, but if the moderator or really any of the participants are bad, it becomes like purgatory.
And I like the feeling of getting encouragement, yes, but I didn't get near enough critique. So my advice is, make sure that you don't end up in a scam workshop where people are sucking your pockets dry and not providing any service other than cooing.
