Real life

I am starting what should be the final year of my PhD. God, it feels like just yesterday that I started this journey. The end of this journey means the beginning of a new one soon and all of the strategic planning that goes along with it.
I admit, I am scared.
Until now, if I screwed up my life I could always just go back to graduate school and get a degree or something. Now I have to face the end of the proverbial line.
I have to grow up and be responsible and get a real job.
After all this, I am so uncertain about what I really want to do now that I am going to be a grown up. Should I follow the primrose path to the Ivory Tower? There's a position open that is tenure track at one of the seven sisters. It will be the first of many job openings this year. Do I take a postdoc research position in the hopes that in a year or two I can find a tenure track job somewhere? Do I want to do something different, be a policy adviser, a corporate scientist, a government scientist, start a company, etc...The list is simply too long to put down.
I am reading several books about making this decision as a scientist (of course I am, what's the first thing a scientist does? background research). They suggest, as many career books do, I make an inventory of pros and cons about my experience as an scientist in academia and use this as a guide. The problem is there are days when I love my job and days when I despise it. It isn't that I don't like doing benchwork (lab work); I can't do it every day. As an academic, I don't have to. My big fear of academics are 1) their inflated egos make it difficult to form real, trusting connections. Everyone is always competing with each other and 2) Will I ever have real time to spend with Senior Jefe, because the longer we are apart, the more apparent the strain on our relationship is. I don't want to fracture us because I pushed this too far, too long and too hard.
I keep hoping my path will become clear, but I feel like more likely than not I am going to have to approach this with the spaghetti method (i.e. throw everything at the wall and see what sticks). That seems scary too.
