Luck matters more than we are often led to believe. One can generate luck, to an extent, through persistence. Leonard Mlodinow has written two books that you might find both resonant and uplifting: Feynman's Rainbow: A Search for Beauty in Physics and in Life , and The Drunkard's Walk: How Randomness Rules Our Lives.

In the long game, it isn't about the degree nor the piece of paper.
