Is it though? It's about as inspiring as Albert Einstein is for physics students. In general, taking inspiration from a genius is akin to the American Dream of becoming a millionaire when starting as a dish washer. The world doesn't work that way and most people will be happier and more successful by not aiming for the stars...
Don't get me wrong though. Back in university I loved reading these things and it is still nice to read them. But I would be careful to derive anything beyond amazement from it. It can be very frustrating to see how much you struggle with simple things, while some Indian clerk without any formal education shows you how its done. And you have to admire Hardy's character for not feeling the same way, or at least to a reasonable extend, not showing this feeling.
