Resolutions? Good idea or waste of time?

Ah New Years day... a time for a fresh start.  Lofty goals usually follow.  The gym gets REALLY crowded, but within 5-6 weeks, its back to the old regulars again.  Why do so many people make huge resolutions that are bound to fail? I am not a fan of sweeping and broad resolutions.  Don't get me wrong, setting goals is important to achieving any form of change in your life.  Change comes from the little things we do every day, not huge changes in lifestyle that are difficult to stick with.  Most people try to make too many big changes at once, and as soon as they slip up they just quit at all of it.  I prefer the bite size goal approach.  For example, this week I want to write in my blog daily.  Next week, maybe I will add another small goal (drink one more glass of water a day) ON TOP OF this weeks goal.  Sure I will mess up and skip a day.  Heck, sometimes I have a whole week that is not healthy.  But the important thing is to get back on that horse and keep on trucking.  This is the only way I have been able to make any changes in my life that last.  How about you?
