I'm not making any resolutions this year. It's not that I don't have any aspirations or that I don't think I can improve upon my life. I do, and I can. I've always seen New Year's resolution's as an invitation to failure and easy excuse to procrastinate. "I'm going to start eating healthy this year!" and "In the new year, I'll exercise more!" seem weak and forced. Something you declare to the world so you feel like you're moving forward; so the fresh January calendar can feel like a new beginning.
I prefer to make changes in my life as I see fit. Why wait until January 1st when you can make the change in November or May? If you want to improve your health, do it. If you want to lose weight, do it. If you want to go back to school, do it. If you want to spend more time with friends, then do it! Life is far too short to use one day a year to make the changes that ultimately shape our lives.
You don't need an excuse or special day to make the most out of your existence. So many people make resolutions, break them a week later, and make the exact same resolution the following year. If you keep waiting for a metamorphosis, you'll wait around forever in some depressing cycle of half-attempts at living a whole life. Get motivated, get up, and live your life on purpose.
It's not going to be easy, but it's going to be worth it.
