If you want to achieve greatness, you have to be willing to sacrifice everything. You need to be wiling to go broke, literally, figuratively and mentally. You need sharpened focus and a heightened ability to compartmentalize your life.
I believe I have that in me. And I think the only thing that holds me back is my desire to be great at too many things.
Sometimes at odds with this is my desire to be a good human being. Or even be a happy human being. It is a daily battle for me as I struggle with bi-polar disorder, but I think I am winning and I actually believe it allows me to forge the path I walk through this world. I bend, I do not brake. I am a rock others break themselves against. Everything I do is focused around where I'm heading and unfortunately anyone unwilling to take that journey gets left behind. Some really great travelers... But it is not for me to decide. Everyone has to make their own choices in life and it is up to them to decide which path they take.
