Yeah, I love these collections. I endorse timestamps, I do the same thing in various ways. And indeed, I'd say, "try to add a little context whenever you write something down", having many notes of a single word, which was fine a day later, but useless later than that.

"New road layout", I'm also often annoyed at the way this is done. But OTOH, I guess in practice "put the sign up and leave it up" works ok, because people who drive the route regularly know the sign isn't *new*, and people who don't know the route recently will either benefit from the sign (even if it's years later) or not know the area at all and not mind whether it's changed or not.

The "just" thing really annoys me, especially that the statement often has much the same factual content but completely opposite import. Saying, "if you want X, just do Y" implies it's easy and we shouldn't worry about it much, whereas usually Y looks superficially easy (e.g. "stop putting cigarettes in your mouth and lighting them") but is actually really hard.
