Help with thesis statement?

I think it's a great thesis statement with the exception of how I don't really see how innocence or experience fits in your past experiences. You might need to change that, but other than that, the wording is perfectly fine. For example, if they're learning from their bad experience, it wouldn't really be showing innocence. Are you feeling innocent through your past experiences? :/ How would their situation be when they are motivated by their past? Do you mean "gaining experience"? Maybe you should use another word beside experience. It probably sounds weird because you put the word "experience" twice in one sentence. :) If you're totally stumped, just change the "innocence" part. :)
