Book Reports / A long way gone by Ishmael Beah - critical essay (where to start?) [3]

Hello
I have to write a Critical/Analytical Response reponce on the novel, A long way gone by Ishmael Beah. The topic is Discuss the idea(s) developed by the author in your chosen novel about an individual's inherent ability to adapt to some of life's most difficult circumstances. I am having troubles of where to start. I understand that Ishmael went through various hardships through his time in Sierrea Leone but i do not know what to state for a thesis or for my 3 central ideas (paragraphs)

Thanks for any help!
