Part of the fun of being in IT, is explaining things to people that that are common sense to me, but unacceptable to others, until they go through the pain that I have been through. Maybe it's true of any industry. Making a suggestion, i.e., here's a better way, and being told, thanks but we will stick with the way we do it, just try and make it work.
Maybe I don't present my advice as strongly as I should. I mean, it's not really advice anyway, as much as "Put more than .50 cents in your gas tank when you go to the gas station", is advice. But then I am told, "Well, .50 cents gets me there, and at the gas station, I can wash my windshield. So this is better, isn't it? So here's one dollar, for today and tomorrow."
I have to quit breaking in new business owners.
