There is a reason for your existence and that reason is supposed to be expressed through your unique gift.
Can you name your reason for being? Can you articulate it clearly?
If you can, you are halfway there. Now ask yourself:
Does my reason excite me? Does it fill my heart with joy every time I am engaged in it? If you can't confidently say "Yes" to these questions, it is not your reason.
It is something you picked up along the way to serve someone else's expectations of you.
"If I want to be free, I've got to be me!
Not the me I think you think i should be, not the me I think my parents think I should be, not the me I think my spouse think I should be. If I want to be free, I got to be me! And I've got to know who me is." -bill gove-
