The true test of intelligence is who you are and what you have made of your life.
Only problem is Esmeralda, "what you have made of your life" is highly subjective.
Some people would consider "making something of themselves" as getting a large bank account.
Others would consider it to be skilled at something they can make a living with, and can feel good about doing (like the Amish).
Still others would consider it to be able to provide for themselves and their loved ones without hurting anyone else, as well as being able to defend those who can't defend themselves.
You can make a lot of money on Wall St., or in real estate, or in being a Washington lobbyist (choice 1).
You can make decent money building furniture or growing crops, and you can feel good about the craftsmanship or green thumb that you have (choice 2).
Or...............like me........................you can feel good about spending 20 years defending this country, and spending some of your time helping charity causes like feeding the hungry or rebuilding homes (like the Navy does on occasion, when they are asked and have the chance), yet you retire on a modest pension and are happy with your life.
Success has many different faces. I fall at the lowest level of the scale I presented you with, but yet consider my life to be a success, as well as consider it to be a life well lived and made well. I have enough to eat, a roof over my head, a shower to clean myself, and enough left over to keep me entertained (as in cable TV and internet).
Some have called me a failure, because they thought that my standards should be as high as theirs.
Fortunately, I didn't share in their delusion, which is why I am happy and content, and have been retired for the last 8 or so years, and I'm only 49.
My life has been a success. I've helped people, I've saved lives, and I've made a difference in this world.
That means more than money.
