I'm struggling with the same thing. One day I left my insulin at home, and I was going to wait for my lunch to go get it, even though I was already running high- my boss looked me straight in the eye and said "you should get it now. Your health is important." I really saw it as something that could be put off, but to have him say thy really snapped me out of it. The only way we can be better is if we take the time to test frequently and take our insulin on time- and that comes first. Two minutes to check/correct will not be the end of the world.
