One central rule that dictates my entire existence? Initially I was going to post a sarcastic response, but then I got to thinking about it. What is my central motivation in this life?
1. I want to enjoy my existence.
2. I want to be proficient in many different areas.
3. I want to be successful.
4. I want my family to be happy, healthy, and clothed, with a stability they can depend on.
If I had to choose from all of the above, I'd choose the 4th. But the 4th could also be looked at as the same as the 3rd... since that is my definition of success. And the 3rd and 4th are an essential part of the 1st. How can I enjoy my existence without 3 and 4? 2 is automatically fulfilled in everything I do. That's just how I operate. If I do something, I learn all I can about it, make lots of mistakes and learn from them, and then eventually reach a level of proficiency that satisfies me.
I was talking with my friend about this post, asking her opinion on it... etc. It was during that conversation that I realized the common denominator between all 4 of my "rules". The "rule" that decides how I live is living according to my God-given destiny and purpose. It encompasses all 4 of my rules and then some, and it's the one common thread that binds them all together.
