Success is accurately measured by the joy and peace you feel within you, not by the things you acquire with out.
A miserable rich man, is he a success? (Perhaps by the screwed-up values postulated today, yes, but to any rationale person, no).
Do you want to spend time with a miserable person or a joyous person (remember that next time you are miserable).
An unhappy powerful man, is he a success? No.
A cheerless, gloomy and bitter celebrity, is he a success? No.
If you can be at peace no matter what your circumstances, are you a success? Yes.
There are many successful people in the world who are not rich, not powerful and not celebrated. They are at peace, happy and joyful. This is real success. Don't settle for phony success.
