Being True to Self?

How true am I being to myself?

I grapple with this almost on a daily basis - the constant back and forth of what I am doing, what I should be doing, and how it is impacting those around me.

Then again, what is the self to be true to?

Let's be honest - there are portions of all of ourselves that if we were "true" to them, would end in a constantly hedonistic lifestyle that used others, gave all attention to pleasure, and eventually would result in our own destruction. So even the idea of being "true" to myself is somewhat of a misnomer - perhaps more correct to say "being true to those parts of myself which are worthy being true to."

But then I wonder: is there anything that makes those "worthy" parts any less honest or straight than the parts that we ignore? Is there some objective standard by which we judge what is truly worth being "true" to?

Because even our best views of ourselves are foolish and often self centered. I am just as likely to consider those parts of myself worth being true to as necessary (but in reality, they make me feel good or I think I am skilled at them) as I am to ignore others that I really should be true to, but ignore for some reason (self sacrifice because I don't like sacrificing, being kind to others when I don't really want to extend myself).

So when I say I'm being "true" to myself, am I really saying I'm being true to the core of what I am - or merely the core of what I perceive to be myself, which usually coincides with what I really desire. How do I find that objective standard?
