Dror:

When I just started my degree I used to be haunted by these constant thoughts:
I’m not smart enough — If I got a dollar each time I said this to myself during my degree, then I’d be a millionaire and wouldn’t need that stupid degree in the first place.

No one is asking questions? Did they all just understand? Why didn’t I? — It’s almost mystical. When the lecturer asked if there were any questions everyone went silent. Some nodded, others smiled, but no one raised his hand, let alone squeaked something that resembled a full sentence.
He must be a genius! He just answered the lecturer’s question! — There’s always that genius. The one that jumps up even before the professor asked his question with a correct answer.
