in the book to kill a mockingbird what are 3 good life lessons i could use for my essay please help and thank you! and try to elaborate on them please if you can

Don’t judge a book by its cover:

Atticus’s advice to Scout echoes throughout the novel as we encounter various characters, from Mr. Raymond to Boo Radley and Mayella Ewell. With our world more divided than ever, Atticus’s words remind us to reach out to others, to try and see the world from their perspective before passing judgement.

Fight with your head, not your fists:

There are actually two lessons to be learned here – are we cheating? Firstly, Atticus is teaching Scout that responding to violence with more violence never achieves anything: two wrongs don’t make a right. And secondly, that the only way to stop a bully (or an internet troll) is to let what they say slide over you. Their only aim is to get a reaction, so patience and restraint are your greatest allies.

Courage is not letting the odds stop you:

Can anyone say ‘toxic masculinity’? Thankfully we have Atticus, who is firm in explaining that an act of violence is not an act of courage. Real bravery is facing an impossible challenge and having the determination to keep going because you know it’s the right thing to do. It’s having lost all hope and carrying on anyway. It’s being afraid and not letting that fear stop you.
