B+ work while overdelivering


I’m taking steps at work to produce more value for my company, and I now have a list of at least 25 ideas and goals! How can I overdeliver for my company (and myself!), while keeping with the practice of B+ work? Wouldn’t delivering “A”work be part of overdelivering? Or is delivering 25 goals of B+ quality work what I should be shooting for? Thank you!! This work has changed my life!
