Great article as always but I would offer that lowering expectations is a slippery slope. Lower them today, and again next week, and again next month and next year and you'll likely find yourself in a dangerous situation. Share your expectations and reasoning. Offer encouragement and praise. Open up about struggles and frustrations. Allow others to take ownership.
Bring others up to your level and maybe your expectations will not only be met, but exceeded.
Chasing perfection may bring excellence.
