Intermittent Fasting + Meditation. A bit difficult to explain but bear with me. Imagine you wake up one day to a rumbling tummy (happens when you do IF). I noticed that such sensations would lead me to a bad mood. It's a subtle process but one day it clicked that I was "inventing" stories in my head to account for the physiological reactions in my body (due to hunger etc.) . Take it to its logical conclusion and you'll realise that this happens with other sensations, too. Now I am a lot more conscious of sensations (especially the "negative" ones) and it has made me happier and calmer :). The WFH helps maintain IF + meditation schedules, too!
