The first long term job that I quit was trying train my placement or to familiarize him with the equipment that I was maintaining there. After two days he barked that he knew everything and didn't need any help. Well I went on with the finishing of the new office networked computer system and let him have at it. Two weeks went by when things started piling up because he had no idea to repair simple things.
After I was ask to help get the equipment repaired I sent him out of the office and repaired the 20 office calculators that day and was done.He came back and wanted to know what I did to get things repaired and I just said they are repaired now and walked out. Boy was I being a royal pain but don't like know it all as none of us know everything.
A week later went work at the new job and it was a learning on the fly job but at least I had some experience, knew to refer to the service manuals, and knew when to ask for help when needed.
After being gone 8 yrs I went back to work for that employer and found out that guy didn't even make 6 months before he was fired.
As for the BP number they finally getting stable around 135/95 average which the top number where the doctor said he was shooting for. I know meds that work for one may not work another. IT is kinda an experiment to find the right mix.
