Death of a salesman quotes

The world is an oyster,but you don"t crack it open on a matress!
It reminded me of the similar quote from the famous author, philosopher and ruler of Montenegro,small country in Europe and his famous poem and play " The Mountain Wreath".

"The nut is hard and peculiar fruit,you don't crack it ,but you break your teeth"
Life is hard for Willy,he put lots of load on his back,more then he can carry.Instead of taking off some of it, he takes more and more.He can't handle it,he starts getting irritated and annoyed ,and that's affecting his whole family,especially relation with his son Biff.
Life is hard as an oyster or nut shell, it's not easy to find satisfaction and the smooth ingredient called comfortable and enjoyable life.You have to be aware of the traps that come down the road.
You have to go trough tough time in life and be able to find ways to overcome obstacles and stand upright.
For Willy it is almost impossible,his whole life he was trying to impress everyone,his sons in first place.Now when they are grown up and see things ,they get dissapointed of the image of their father.They want him strong and successful,but he is not that guy anymore.
Willy is failing in his career and his private life too.He has support from his wife, but still it is not enough for him , he needs more and more attention .He betrays his wife and sons getting involved with another woman.He fails to find meaningful life outside of pursuing his dreams of the greatest salesman.
