Of course, I too have some resolutions of my own but I'm going to exercise a free technique that doesn't come in a bottle that we, as humans, are given: will power. Yes, will power, the power to will oneself to stick with and accomplish a well-thought out goal. Or, as Oxford states, "a persons power to decide on something and take action." That's my strategy.
I don't mean to be bitter, in fact my approach to 2009 is quite the opposite. I feel optimistic and invigorated to implement my own list of mind, body, education and career goals just like the next. I also believe that you don't need one particular time of year to implement these goals; however, the turn of the new year is just so darn handy, the slate is wiped clean (per se) and it's a time for new beginnings.
Three cheers for will power, and if you get suckered into the blaring advertisements and buy into the plethora of products and they actually work for you (not just as a placebos) then all the fucking power to yeah!
