Keep in mind that the number of right answers you knew or how good your grades were in school do not measure your success later in life. Your success is measured by how many answers you do not know, how many times you fail, stand up, learn from your mistakes, make corrections without blaming, lying or justifying, and then move on.
That is why people who have good grades do not necessarily do well in the real world. Real life is not made up of right answers. Real life is made up of multiple guesses, some of which turn out to be right and many of which wind up being wrong. - Rich Dad
