Full Idea
Knowing whether or not a man is free doesn't interest me. I can only experience my own freedom.
Gist of Idea
Whether we are free is uninteresting; we can only experience our freedom

A Reaction
Camus has the right idea. Personally I think you could drop the word 'freedom', and just say that I am confronted by the need to make decisions.
