Waste is part of life. Especially waste as a byproduct of good faith attempts. Is it better to avoid creating waste? Yes, however; perfection is the enemy of progress, no one is clairvoyant, and best is conditional anyway.

My point is: you didn't do anything wrong. The mere fact you're thinking about it reveals you've grown wiser for the experience. Kudos, friend. Thanks for sharing.
