If change is worthy of being made, it should be made. Don't wait until the time of year when people get suckered into feeling all gushy about having to write different digits in the year space on checks for textbooks that they can't sell back. By all means, if you want to make a change in your life, if you want to break out of the routine, go for it. Just remember that the idea of changing is more attractive than actually changing. Changing means breaking routines.
Routines become routine because they are efficient or comfortable, no matter how lifeless.
We're the way we are for certain reasons. Bad habits bring pleasure or comfort, even though it may come at high cost. We aren't doing the things we should be doing because we're lazy, busy or weak. If your bad habits don't bring you some kind of pleasure, even fleeting, you need more than a weak new year's resolution to change your life. If you are going to change, make sure you know why you're changing and how you're going to make the change plausible.
