I'd like to append "at least twice if not more" to this excellent LPT.

A lot of people do something and instantly rush to report it to LifeProTips as must-have advice... when experts in that thing just wince and roll their eyes at how often it turns out to be massively counterproductive.

I'm a business consultant and routinely destroy bad advice here, not out of meanness, but because it's just such BAD advice, and if it leaves a positive impression on some people it could hurt them. Ditto stuff that reinforces social anxieties instead of facing or actually managing them (with the most common of these suggesting stupid lies to avoid social situations).

Often the advice is from someone who either thinks it makes sense (when it sometimes just doesn't), or it worked for them out of some freak coincidence. Either way, it's not a LPT the vast majority of the time, and in some respects can cause actual damage if followed.
