1) Use your damn phone to check the time. Be a grown up and get a watch. No one of these tick...tick...tick 1X per second quartz movement pieces of garbage, either. An actual grownup mechanical watch. You don't need to break the bank and go out and get a Patek or anything like that. A mid level Hamilton is or something like that is perfectly fine, and should be affordable to anyone with an office job. Pulling out your iPhone to check the time just makes you look like a kid. Which is fine if you are a kid. But you aren't a kid, so get a damn watch.
2) Wear rubber soled "dress" shoes. Sure, you'll look prescient if a basketball game breaks out in the middle of the workday and you had the foresight to show up wearing athletic shoes in disguise, but for the 99.999999% of the time that you don't suddenly have to perform a surprise athletic feat in the middle of the office, just wear real dress shoes with leather soles. And if you're one of these "fight for 15" types, an added benefit is that you can buy some Aldens or AEs that are actually made by decently paid craftspeople in the US and not produced by children in some sweatshop. I'm amazed by how many of you people are all "I care about working people and want everyone to make a living wage," then when it's time to go out and buy clothes, you load up on cheap sweatshop products. You people make me sick!
That's my list for now. More to come. Feel free to add your own. Or don't. I don't care. Fvck you.
