What You're talking about, or so it seems to me, is people who - (I've done it and will do it again, and that's how I know)- obsess about what they think they might be, or even worse, who obsess about what others think they might be.

My point is, that when you accept that you are yourself, consistently, no matter what you do about it, you also realise that there is no point in obsessing over what you might or might not be.

Whatsmore, no philosophy, creed, religion, wise saying, insult or judgement can sum up something as ungraspable, constantly changing and free as the human spirit.

Wow! Don't you think? (bearing in mind the bit about understanding others etc)
