One of Einstein’s biographers writes: “We can take heart that it is not necessary to be a good student to become Einstein.” Considering that Albert Einstein brought about a veritable revolution in twentieth-century science, this statement would seem to be something of a paradox. But it is quite true. One of his teachers summed him up as a “lazy dog” and he was even once expelled from school, so inept was he in his studies. He was not even able to gain admission to the Zurich Polytechnic at the first try, because his marks were not high enough. It took a whole further year of hard work to get him his admission.
No signs of his extraordinary genius appeared until he was twenty years of age. But then he began to work really hard and ended by outstripping all other contemporary scientists. With the passage of time, his fame, if anything has continued to grow.
He should banish despair, for there is no end to possibilities in this world. It is simply a question of being determined to make the best use of them.
