I choose to define my success in terms of humanity. My goals do not involve material gains but involve the well being of humanity and future of life on earth. If i do manage to accumulate wealth in the process, i plan to re-invest it for a better future for the next 100 generations.
The american dream doesn't spiritually satisfy me. It limits the benefit to only me as a person but not the next 1000 generations that will exist.
Even the founder of Huffington post said " “As long as our culture defines success as money and power, we’re stuck on a treadmill of stress, sleep deprivation, and burnout.”" its a never ending rat race.
Life its not about a rat race against one another, its about a race against time, against our limits.
To summarize my success- "My success lies in the success of all mankind and life in universe"
Or as dalai lama puts it-
I'm a thinker, dreamer, doer and a strong follower of stoicism. I have a passion to learn and apply that to make the world a better place.
