For a while now I've tried to cultivate the habit of not trying to have opinions about everything. It's quite liberating to say: sorry, <thing> may be important, but I just don't have an opinion about it at the moment.
There is something freeing about acknowledging you don't need to have an opinion and something enlightening about knowing you shouldn't have an opinion--especially on a topic that you aren't truly informed about.
My favorite meme on the subject: "Marcus Aurelius has already released you from the obligation to have a take":
> 52. You are not compelled to form any opinion about this matter before you, nor to disturb your peace of mind at all. Things in themselves have no power to extort a verdict from you.
