I am not big on giving any particular day significance over another. I see life as a journey, one moment at a time. The ultimate hike. Each day is important. Remember, the goal is not to reach the end! :-) It is to enjoy the trip.
January 1 does provide a touchstone for many people. An opportunity to reflect based on timing, for us Earthlings, that is determined by our planet's distance from the sun in our galaxy. Fundamentally, that is what generates the point of reference we call a "year". When was the last time you thought of it that way?
I would challenge you to consider this as the first day of the rest of your life. You can choose to make it a better day for yourself. You can choose to make changes to better your life. The changes don't have to be monumental. Incremental works very well.
I dare you to step out of a box you might find yourself in. Remove something from your life that is bothering you. Confront a fear - Head on! Challenge it! Force it to explode, and strengthen yourself in the process by exposing that fear as a fraud.
Explore CBT / RET as an effective, potent, long-lasting tool to deal with your fears. Do a Google on Cognitive Behavioral Therapy, also know as Rational Emotive Therapy. It works, it is freeing, and it will make you a better person.
Action Cures Fear. Say it aloud: Action Cures Fear. Action also cures Frustration. In fact, Action cures most all ills! Try it.
How do you feel? Are you Happy? Frustrated? Bored? Sad? Many times negative feelings are generated when you choose not to realize your dreams. When you choose not to be the best you can be. When you choose to accept mediocrity. Let's be blunt - it is your life. It is up to you to make positive changes. Nobody is going to do it for you, and nobody wants to hear you whine.
Other people do not hold you back. You hold you back. Let's be perfectly clear about that. Unless you are serving a life sentence in prison without parole, you are in full control of your life.
Make a change. Use Jan 1, New Years Day as an excuse if want to. I prefer you not need any certain day to motivate yourself.
Today is the first day of the rest of your life. Are you the best you can be?
