Back Where You Belong

There is a job posting located in the city where I lived for eleven years. I should apply, but I hesitate... I search through the minefield that is my current set of feelings and concerns.

Why hesitate?

1) I've applied at this company before and they didn't call-i.e. waste of time.
2) I, personally, don't want to ever "go back" in my life. I hope to always move forward. Then I think, does going back mean you were wrong to move away in the first place? If you go back-will you fall back into all the unhappy places and habits you were in before you left?
3) It's been four years. People change-friends move on-My view of those friends has changed. I kind of like them where they are in my life right now... If I go back then that, too, will change.
4) I have friends where I am now that I would like to keep. I think I'm better at making friends with the right people for me. I don't want to lose them.
5) I hate the weather there-but then ask me again in February when I hate the weather here and I might change my mind.

Now I ask- are these good enough reasons not to apply? Am I simply avoiding moving on? Or do I truly not want to go back? If I chose not to apply, will I miss the only job that will hire me for the next six months? I'm stuck back into being frozen in place-the rut of wondering how best not to make a mistake...

Truth is there are no right or wrong answers to these questions- the only thing is this- either I chose to apply or I chose not to apply and the rest will happen as it does-right or wrong.
