Chalk this up to learning:
Glossy curriculum is uninspiring, and mechanically applying it feels like a bad use of your training and ideas, but if you depend on a team of volunteers to lead your students, volunteers who haven’t been to seminary and who have day jobs and kids and aging parents, then tinkering with the glossy curriculum each week so that it feels more like “You,” only makes things harder for them.
If you’re going to tinker, maybe do it early, all at once.
