Perhaps you could collect candid feedback on your writings? Don't ask friends or close colleagues, instead search for those in your field whose opinions you respect (but may not agree with)? More broadly, perhaps find/form a community of individuals with similar interests (organizational leadership and change) and join them? In particular, seek out people with different backgrounds than yourself. I've found book authors on these subjects to be especially open to dialogue, if your opening letter connects your question to their work.
