I feel it is better that people underestimate you rather than overestimate you.
Those who are underestimated are not dragged down by others.
Those who are underestimated are not pulled up either, but at least you can climb up on your own to make up for that.
To overestimate someone’s skill leads to inefficiency in work and wrong attitude, but to underestimate someone at least opens up space for improvement and development.
Shouldn’t we go for the right estimation? Well with so much subjectivity in human nature that is a pipe dream.
