my mom taught me the phrase "rearranging deck chairs on the titanic" meaning to do something that will end up being for naught. i like that one. the other day, used the phrase "make hay while the sun shines" in a conversation with a friend. i was so surprised when she said she'd never heard it before, but i hear new ones plenty often too. even subscribe to "phrase of the week." some of my favorites to use include: "feast and famine," meaning too much and too little, lacking balance. "can't see the forest for the trees," meaning to be so entrenched in details you're unaware of the scope, or even the obvious. and "doesn't know [blank] from adam's house cat," means to not know someone to such at all, or to such a degree they may as well be someone else.
