Remove E from ego and go on.One can have confidence but not ego. Confidence is very healthy. But ego is never healthy. It will spoil our progress.
Many say "Too much ego will kill our talent".
One should not allow ego to lead us. It may lead us in the wrong direction. Finally, it may ruin us.
Ego spoils a person in many ways. It may spoil our prospectus in the career. It may make us alone in our life. Ego will make us more stressed and we will become very critical. It will make us greedy and may take us away from happiness.
So forget 'E' in EGO and go on with enthusiasm for progress.
