I don’t make New Year’s resolutions. If I’m going to make a change, I do it right then. Why put it off until next year when you can Do it Now? Aside from falling back into bad habits , procrastination and basic laziness short-circuit most people’s attempts to establish new patterns.
It may take longer than you think to establish a new habit — depending on the behavior you’re trying to change — but that’s no reason to hold off on doing it until a particular date. Instead, you should start immediately.
Whatever you do, do it. Keep doing it. Make the changes in your life that you want to make. You can’t control the outside world, but you can change how you interact with it. So do it.
