There is no nobility in underestimating yourself. False modesty can only turn into a curse. Be yourself, yes, but not at the cost of amnesia. People often forget that we are here to improve ourselves on a daily basis. Whatever happened in the past doesn’t have to affect your tomorrow: today is the game-changer. And it is very important that you measure yourself against yourself, not others. Get the right amount of estimation, leaving little room for underestimation or overestimation. After all, you ought to remember that you aren’t the person today that you were yesterday. Not sure whether this is a good thing though.
