SAT Examples for "Quality or Quantity and Success" Prompts

I’m looking for examples to use for the prompts “Do people achieve greatness only by finding out what they are especially good at and developing that attribute above all else?” and “Are all important discoveries the result of focusing on one subject?”.

If you know any examples of people who made an important discovery in Field A because of their knowledge of Field B, would you please post them for me? Thanks!

Steve Jobs was very good at selling things and making them look pretty, which is how he achieved such great success in the PC revolution.

Thank you!
