Though it's tempting to go out six nights in a row, then come home and binge on nachos and pizza, restrain yourself. Even if it's just every so often. It may seem like you're light-years away from anti-aging and self-care routines, but you're not.
The choices you make now with your physical and mental wellbeing will determine your future health. So, be kind to yourself. Find hobbies, foods, exercises, books, and places to travel that make you happy and do more of that, more often.
