New year, new you!

We do this every year, commit to something new. Overcome a new or existing challenge. Its like we hit reset on our lives and start over. But do we? Why do we wait until the "New Year" to start something that is so important to us that we promise ourselves to change? If we are dedicated to improvement, shouldn't we commit to this year round? Starting a new goal at a set time is not a bad thing, but it carry out that goal and follow through all year, not just the trendy time.
