I look across my life and see many failed attempts at following through on resolutions and vows of various types. As an adult, I am no longer surprised by this. Each year that passes is a new understanding of my personal failures. I am sure that most people, like myself, come to this realization once they have left the comfort of their parent's home. I am sure that some realize much earlier than others.
The encouraging thing about failing at resolutions and goals in particular is that you learn to do them the right way. Each time you fail it is important to pick up and go at it again. I learned some very important tips concerning personal growth by using measurable goal-making from Chris Oatley's Artcast just this last week.

The hard part about living your life, especially to be excellent in every area you can be, is that nothing really stays the same. The only exception is God and His goodness. We constantly have to be on our guard concerning everyday challenges. Is there a set way to do a task or requirement? Some times there is, but rarely. Life consists of improvisation in repition. You can do it well, if you have done something like it before. But do not count on it working exactly the same way. So, life feeds art. It gives us due inspiration, because like life, art is a continuous process of change and growth.
Don't give up on your goals! Firmly stand in the gap between your starting point and your goal. Be excellent in your career pursuits, your family life, and hold high the tenets of doing right by others in as many ways as you can! Stay the course, because none of us have it easy and from time to time we can learn from each other's failures.
