Sounds to me like you have a negative motivation (away from) strategy versus a positive (towards) motivation strategy. In my experience, you can either 1) change your strategy to a positive, 2) leverage your existing strategy, or 3) both. But my first question is, why? If you are happy now, what says you must change? As you say, you are already rich so anything else is a bonus. Enjoy what you have right now and ignore the social idea of "bigger, better, faster, grow, change, evolve"--just enjoy the heaven you have now.
Life will throw some changes your way soon enough, and then you will be motivated to act for sure!
