Mojo second episode

What does the quote from the video, "mistakes can make you smarter" mean to you? 

It means that mistakes make you understand what you did wrong so the next time you do it you should remember what you did wrong and do it better this time.

How can we learn from our mistakes? Talk about a specific, recent example. 

I play handball so if i do a mistake like not attacking the ball then my trainer tells me what I did wrong and the next time I try to attack the ball and I often succeed. 

If you were building a robot and kept "failing,” what would you do?

I would smash it into the wall.
