You know how it goes at the end of December. You get together with friends or strangers, watch the glittering ball drop, kiss and toast, wish everyone a happy New Year. Or maybe you eschew the party and go to bed at 10 p.m., which is invariably more enjoyable if you ask me. Either way, you wake up the next day and vow to stick to your resolutions...or actually make some this year. About half of Americans make New Year's Resolutions. We pledge to start exercising or stop gossiping or finally write that book (you know who you are). We start the year with good intentions to be more positive and drink more water. And this time,  this time we're really going to stick to those life changes. We swear. But about three-quarters of us fail to keep our resolutions. They're too ambitious, too vague, no fun, or we flat-out forget. By late March or mid-February or January 15, those resolutions have become merely wild-eyed dreams we had when we were younger and less naive.
