About my favorite author

I’m inspired by him because he is an example of perseverance and endurance in the face of adversity. I'm influenced by him because his books taught me that I have to fight for what I believe in and that I should forgive people.

this was pretty much perfect, just it is much more common to use the expression "to fight for what I believe in" instead of "fight for my ideals". Also you must say "that" again for the second thing he taught  you :)
