NOW, WE'D NEVER, EVER, tries to stand between you and your first marathon, a major weight loss, or the job of your dreams. Thinking big and having big goals - is important, especially as you set your sights on a new year. That said, sometimes thinking a little bit smaller - in fact, maybe making just a few minor tweaks to your routine - can yield some pretty big W's, too. That could mean just swapping out a single drink of the day for water and watching your weight plummet. Or using a simple timer at your desk that will up your productivity tenfold. Or even doing some very small, invisible exercises that will have a major impact on your sex life. Best of all: None of these tricks costs a cent, and none of them takes much time.
