For me it’s driving while under the influence. If you couldn’t tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can’t fathom. I’ve only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.
I work in gamedev and its really baffling how rare is for someone to read the docs. I’ve already solved so many issues by just reading through the related docs and discovering a feature that does exactly the thing we’ve been trying to solve with a workaround, or had a overcomplicated process for doing, while it could have been a single function/API call.
Read the docs people! You probably have a lot of downtime while waiting for stuff to build/compile, and just rabdomly (or systematically) scrolling through the reference or docs of the library/tool your working with, even when not looking for something specific, may save you a lot of time in the long run. Knowing what are your tools capable off is well worth the effort.
