Not living up to one's potential

I'm certainly not. But I don't say that because i'm mired in some deep depression. It's merely the truth...and something I think about daily. And it drives me...in a way. I'm saying all this because I saw the Almighty Oprah on a Larry King repeat. She was speaking about her greatest fear...not living up to her potential. What really struck me, though, was her remark that at around age 50, you realize you've got less time left than you've already lived. Well, POSSIBLY, lol. But, OK, so it's generally true. Oprah's comment isn't a new idea to me, so I give myself credit for thinking so deeply at such a young age. Hell, I could die TOMORROW. But it just again had me thinking of TIME...ticking, mercilessly. Feeling like RIGHT FUCKING NOW is the PRIME of my life...and I need to DO something...BIG. Ahhhhhhhhhhhhhhhhh!!
