Computer related:

Don't be your family computer savy guy, you just found yourself a bunch payless jobs...
Long desks are cool and all, but the amount the space they occupy is not worth it.
Block work related phone calls at weekends, being disturbed at your leisure for things that could be resolved on Mondays will sour your day.

Buying stuff:

There is expensive because of brand and expensive because of material quality, do your research.
Buck buying is underrated, save yourself a few bucks, pile that toilet paper until the ceiling is you must.
Second hand/broken often means never cleaned, lubricated or with easy fixable problem.

Long story short: someone else's advice ITT reminded me a uni professor talking about a student hurting themself with glacial acetic acid. That reminded me how often I'm using alcohol vinegar for cleaning (alcohol vinegar is basically one part of glacial acetic acid for 24 parts of water), but I don't see people doing it often - instead they often buy expensive cleaning agents that they use everywhere as "magical" solutions.

Why is it called "glacial" like it's got something to do with ice? Why not simply "concentrated", which it is? Thanks

Glacial = anhydrous. People call it this way because pure acetic acid has a rather high freezing point (16°C), and it looks a lot like plain ice when frozen. (It still stinks vinegar once you open the bottle though.) But once you add even a bit of water, the freezing point drops considerably, so acetic acid solutions don't show the same "ice".

So in colder days, you need to rewarm it back into a liquid. Then people get really sloppy (I know it not just from that professor's anecdote, but from watching it). They say "I'm just rewarming it, and it's just acetic acid, what could go wrong?". Well, it's still a big flask of a corrosive, volatile, and flammable substance.

In the meantime, the same people doing dangerous reactions like nitration (it literally explodes if you let it get too hot - spreading nitric acid, sulphuric acid, and some carcinogenic solvent) "miraculously" pay full attention, obsessively taking care of the temperature of the ice bath.

Part of the advice that I mentioned in that comment chain is that - smaller dangers are still dangers, do not underestimate them.
