I was reminiscing about previous jobs when I started thinking about how one of them taught me an important skill for this one:
Even if you're a total introvert who hates mornings, fake a smile and say 'morning' or 'hi' to people. I got dinged at my annual review - that I never had again in my four years of working there - for 'bad attitude'. Everyone here is really friendly and it makes a nice workplace, so I fake it (and assume a bunch of them are as well).
One other one:
I will never again work at a place that doesn't have a time clock or some other set policy for tracking hours. The two places I did were unorganized, chaotic messes and the time clock was a big red flag for that (the one, the boss' wife was too lazy to figure out hours - and I don't know why they didn't just use a payroll company - so everyone was salary. The other, all the resources I needed for my job were just dumped in folders or cabinets, the two bosses yelled at each other all the time, they let their kids come in at night and play games - including installing stuff - on the company computers, etc...)
Y'all?
