I want to be both safe and rich.
I consider myself relatively safe in that I have the three pillars of (pending) retirement assets: pension, investments, and social security. Because I am very frugal, any one of these assets will be able to independently cover my needed retirement expenses and much more. If I retired today at age 54, my pension would provide about 5 times my expenses (ignoring income taxes), my investments would provide about 6 times my expenses (at a 4% SWR), and social security would provide about 2 times my expenses beginning at age 70. These ratios should continue to rise since I plan to remain in the accumulation phase after retirement. So my safety margin is large, baring some sort of economic armageddon.
While my investments are not 100% in equities, they are 70/30 with no immediate plans to change. The most likely scenario is that I will live off my pension for the rest of my life and let the investments "ride." In addition, I will continue to add new money to my investments using unspent pension and eventually unused social security funds. So I should be rich using the definition provided by the OP.
While money may not buy happiness, having a sense of financial security is and will continue to be a big step in that direction. Having the option to splurge on big activities (e.g., summit Mt. Everest, sub-orbital flight) will bring satisfaction regardless of whether these activities are actually realized. I will have no regrets about leaving the money to charity when I die.
