The advice I would like to give KAIST students is to think big, think different, and think simple.
First, thinking big involves looking at the big picture rather than the small entailing details.
Secondly, thinking different is exemplified by Claude Shannon, who was the only engineering that explored outside of the world dominated by analog circuits to become the founder of information theory and digital electronics.
Finally, to think simple is to focus more on the simple rules, such as F = ma, since the most important aspects are often the simplest.
