Just not my time or is it simply just not in my hand of cards?

It's just one of those days...not a pitty party kind of day, but just a day of doubt.  My head runs a thousand different directions when it comes to money and how to pay bills.  Then I go to school, which kicks my tail.  I know I'm not dumb, but who am I kidding with the classes I'm taking? Do I really have it in me to succeed onto a different level? I can't pronounce half of those words and I'm expected to take the hardest test of my life in five months....and pass it!! Did I mention the national pass rate is 54%? Yeah, I know....maybe the jokes on me...I have a plan in my head on how I see my life playing out....but most days it feels as if that will never happen.  So I ask...is it just not my time or is it simply just not in my hand of cards?  I have motivation and I have drive...but the direction I need is out of my reach...always...I know what I want and I see what could be mine, but in some aspects of my life, there is only so much I can do on my side of the fence...where to go? what to do? Do I question some things or let them be? Where is this life of mine going?
