Everything in moderation. It might be the least exciting advice ever given, and it might also be the best.
Think about it. Pizza is great. Pizza for every meal, every day, forever? That is a cry for help with extra cheese. Sleeping in is wonderful. Sleeping in until the sun goes down is just being a very relaxed vampire.
Work? Good in moderation. Rest? Good in moderation. Even fun needs a balance, because a vacation that never ends stops feeling like a vacation. It just becomes your couch, but farther from home and more expensive.
The funny thing is, most of life is not about finding the perfect amount of one thing. It is about having a little of a lot of things. A little work, a little rest. A little healthy food, a little junk food, eaten without guilt because you earned it by eating the healthy food. A little time with people, a little time alone on the couch recharging like a phone with feelings.
Extremes are loud. They get all the attention. But balance is the quiet friend who actually shows up every day and keeps your life running.
So go ahead. Have the donut. Just maybe do not have the whole box.
Unless it was a really good box. We have all been there.
