I've never used 6-pack holders and I'm remaining silent in real life almost all the time, so that's not my learnings

But Lisa make me think about myself and my far-fetched problems, which is so silly in comparison with her life. I mean, now when I'm starting to worry, I can just think about I am almost adult, so maybe a bit more independent due to this, and I have no worries about college money for future, cause it's possible to study for free - so her life is harder, but she didn't give up, and it gives some hope

Also, I respect her possibility to go everywhere, and be active, when it comes to struggle for her rights or beliefs. I'll be glad to accept this strain from her, but I suppose, I need more time, although I understand, how it is great and useful to be brave :\
From her relations with Hugh and Nelson and from Marge I also understood, how stupid are tryings to change other person. If you can't accept person "as is", it's better to find someone else, or try to discuss it, but without pressure and making victims from yourself.
But anyway, sometimes all this learned lessons don't work. Only thing I kept from her - it's vegetarianism, other conclusions I accept theoretically, but can't always use practically, cause sometimes begin to act too childish :\
