@celes My inability to say No to people has complicated my professional life to no end... I've just read it and I'm going to re-read it and maybe even read it once more! Excellent post!!
@beardedfancyman I hear you! It was the same for me until I realized that I really needed to put my foot down and just say no, because the requests never stop coming. I'm glad you find the post helpful! :)
