Lordy McHeavens, where do I begin? Most of my life is "what not to do"
--If your boss is the owner of the company and not a super wonderful person, don't walk into his office and tell him that he does a terrible job as a boss and that he's running his company into the ground. That is a fine thing to do AFTER you have found a new job, not BEFORE like I tried.
--If
amazon.com says that it will take 2 months to ship your books even though it shouldn't and you need those books this week, DON'T just shrug and think the system will fix itself. It won't. You must cancel your order and call in.
--don't assume that the repair people are doing things right. I did that and it took 2 weeks for the repair guys to find a simple leak in the apartment above me. If I had monitored their doings it would not have raining in 12 spots in my apartment for 2 weeks.
--the Vicodin says "take with food" for a reason. I had an injury and took it on an empty stomach. My stomach then emptied itself several times.
--don't assume that you know what someone's job is. I worked somewhere and was told, "oh, she's the general manager's assistant." WRONG. She was the ASSISTANT GENERAL MANAGER. Big difference! Bad things happened because I didn't know not to assign her to do something for me.
--don't assume that people are normal and sane, particularly when they've had alcohol. They are probably crazy. They might be the fun kind of crazy or they might be the bad kind of crazy where you have to file a formal complaint against them.
Those are just the ones off of the top of my head. I've got a zillion. There are many things in life that you should not do. I've tried many of those.
