As for the second part of the homework, there are many quotes that are inspiring for me, here are few that I've chosen for now:
"If you want to understand the causes that existed in the past, look at the results as they are manifested in the present. And if you want to understand what results will be manifested in the future, look at the causes that exist in the present."
"Since everything is a reflection of our minds,everything can be changed by our minds."
"Everything changes, but nothing happens"
