I feel like Finn on Glee: someone who was always told he would do great things, but whose confidence was lost in the rush to find out what they were.
I was told every day of my life that I was "meant to do great things". Oh, I am still told this to this day. It actually stings a little. I can't figure out what those things are. But this is said to me in such good spirit, I can never reproach a person for it. And why would I? I don't disagree. I still think it's true.
In the distant past, I tried to deal with it by seeing my ventures as biding time: getting ready to pounce, dipping my feet in different waters only to accumulate an evermore rich history of experience.
I don't think that the "great things" I will do in this lifetime will come from sitting still. I also don't think I will ever have some grand epiphany about what I am meant to do or to be. I aim to excel in all that I do. I just need to keep doing that ... and walk away when I don't.
