I struggle with who I really am.
Not in some existential "who and I going to be" sort of way, but in the manner that my true and sinful nature as a human being, the desires of my flesh, cause me to do things that in my heart I know are not good for me, and in my head I know will have grave consequences down the line.
The world tells us otherwise, that what is natural is good, but in my heart of hearts I know this not to be true.
We all share a human condition that has been passed down from the beginning of time. The sooner we come to terms with this arrangement, that we as humans are NOT inherently good and that we are in fact DESTINED TO FAIL, the quicker we will be able to live out our lives in a more appreciable manner.
Appreciable not only to those who we interact with on a daily basis, but more importantly, to the One that truly matters:
 And to Adam he said,
“Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, ‘You shall not eat of it,’ cursed is the ground because of you; in pain you shall eat of it all the days of your life;
 thorns and thistles it shall bring forth for you;
and you shall eat the plants of the field.
 By the sweat of your face
you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return.”
(Genesis 3:17-19 ESV)
