A new haircut is a vibe. A new habit is a life.

Changing how you look gives you an immediate lift, and there is nothing wrong with that. It just runs out, because appearance changes the first three seconds of a room and not much after. What you repeat is what accumulates into an actual different life. One is a mood and the other is a direction, and you can have both.

Enjoy whatever makes you feel good about how you look, and then add one repeated thing underneath it. Pick something you will still be doing in March. Let the visible change be the easy part and the habit be the quiet one.
