Acharya Prashant explains that the true measure of excellence is not determined by one's final position or destination in life, but by the challenges faced and the struggles overcome to reach there. He illustrates this by comparing a student from a remote, underprivileged background who achieves a rank of 2000 with a wealthy, privileged student who achieves the top rank. He asserts that the individual who has struggled more is superior because excellence is found in the struggle itself rather than the outcome. Furthermore, he emphasizes that being the best is not about inherited wealth or status, but about making the right choices and exercising discipline. True excellence lies in the ability to go against bodily comforts and make conscious, difficult choices in life.
