Yes, I believe we can do that, but don't ask me how cause I"m lost in the wilderness myself right now and don't know where I'm going - but I'm still going and I'm still me...if that makes any sense, probably not tho.
the whole Shakespeare quote from Hamlet is something like this: "...this above all else, to thine own self be true, then thou can'st not be false to any man..." I like Hamlet.
If we don't know who we are, how can we be true to ourselves, except by going around telling people "I don't know who I am or what I'm doing"?
Maybe I'm not in the best place to comment on that.
Just my two cents, anyway.
