Today I have a small but powerful life hack for you. Whenever you feel anything less than your best, ask yourself, “What was the very last thing that I ate or drank?”

People wildly underestimate the effect of food on wellbeing. Sure, you might be anxious about that project you have to finish for work… or maybe you just had a coffee and you don’t tolerate it very well but never realized it.

In my experience, food responses are fairly quick and simple. You’re not going to get a reaction that only reveals itself when you eat kale within two days of bacon during a full moon.

With this technique, I discovered that Diet Dr. Pepper makes me sneeze.
