Responsibility?....What's that?

I've been thinking a lot lately about the shift from living life as a student and actually living within your chosen career path. It's really quite interesting to be in that place where you are at a whole new level of learning life skills. For years long before I was ever even in college I had my own little ideas of what life would be like when I was finished with school and out on my own. Somehow my version of reality and the real thing have turned out to be two different things. I'm really quite certain that many people find themselves in such a place in life where they look back and say to themselves "I never thought life would turn out this way." I know that those words have certainly rolled through my mind on occasion.
It's funny (I use the word loosely) how God's ideas for our lives can vary so very much from our own. Or is it the other way around? I think it very much is. Our ideas are often very different than what God's got in mind. Is it to make us suffer? Angry? Faithless? Nope, nope, and nope.
If you really think about it, the bottom line is, life as it has turned out is the way that it is, and things will change, things will shift, be harder or easier but in the end, that's the way it is.
The downside of original sin is that things are no longer perfect and as a result the world has become the way it is and the things that are ungodly run rampant and our lives are affected negatively because of it. It's not a game of chance, nor is it a cruel twist on creation that God decided to place on us just for kicks.
So because my life hasn't worked out the way I thought/think it should, am I somehow right in being angry? The fact of the matter is that I always look around and see the things I don't like instead of the things that I do. How can I enjoy life as a whole if I am focused on the things that I "wish were different?" There's so many great things to be enjoyed in life, why waste the good stuff by focusing on the bad?
These thoughts are just reminding me that I need to keep seeing the great things God has placed in my life and be so excited about where He's placed me and where He's taking me instead of what "I want."
