Sounds like you place way too much value in unimportant decisions. Its a coffee for goodness sakes!
What I would tell you to do is start focusing on minimizing how much time you give yourself to make such minor decisions (like food and drink and similar). Give yourself a set time on the clock for example 60 seconds or whatever. Nothing way out there…and also accept upon yourself that whatever decision you made is fine and it really isn’t important. It isn’t. Hazelnut, french roast regular? What’s the difference. You like them all just some flavors may taste better or appeal more at other times. But realize that at the end of the day there’s no wrong decision in these areas.
