My semester habit stack is boring and it’s working

I’m a full-time student with a schedule that changes every few months, so I stopped chasing a perfect routine and built a tiny stack instead. Every morning: bathroom, scale, one line in the app. That’s it. If a Tuesday number jumps after a late study group and salty noodles, I check the seven-day trend before I react. Last month the line moved down 2.4 lb while individual mornings looked like static. The real win was replacing my 3 p.m. library vending machine loop with a packed snack I actually like—Greek yogurt if I’m home, roasted chickpeas if I’m not—plus a 10-minute walk between buildings. I still have chaotic days. The trend is just less dramatic than my brain. For those in school or shift work, what’s one tiny habit you’ve stacked that survives finals week?
