Don’t judge people with your own parameter of success.The word success definition is different person to person and you just can't judge other's success with your own parameter of success. If you are successful in your field, other (whom you indicate or compare) might be successful in his/her field. You just can't decide your own and come to any conclusion.
Example: If you reached on certain level in ISC where other could not do so far, doesn't mean that others can't get to that height in which you are in. It is just matter of the time and availability one should have for ISC and the success in ISC is yours. However, it must not be taken in our "mind" that others are not successful. Who knows, other may be successful in a field in which you are just a "big zero".
So, if you got success, you should be humble for that instead of comparing others with your own parameters.
