New Job?

The interview went really well and I was asked to start this Wednesday.  Yes, this Wednesday.  I told them I needed to speak with my husband (which was really cool to say) and call her tomorrow.  I also need to e-mail both her and the person who found this job for me with a couple of questions but I think I'm going to try it out.  This job goes until December 31, 2011 and there is the potential that I could be asked to stay on longer but I think that's just the right time frame.   I'll admit, I'm nervous about being able to handle 65 hours a week but the I figured that the worst that can happen is that I can't handle it and I quit it though I hope it doesn't come to that.  To help me decide, I made a list of pros and cons.

Pros
+will earn more money (pay down credit card debt sooner than expected)
+a nice step from a call center where I'll use my skills from the call center and learn more
+the company is located in the same town that I live (only a 10 minute commute max)
+they are willing to give me the hours I'm looking for so I can continue to work at my current job
+only goes until 12/31/11: will give me good idea of whether I can handle a full time and part time job
+if it is too much then I can quit if need be (hopefully not though)

Cons
- I'll be working 65 hours a week- not the coolest
- Will be working 6 days a week
-  I'm so used to sleeping in and I won't be able to do that anymore
- Won't be able to take time off the way I wanted
- Will be difficult to plan holiday parties (wanted to plan a thanksgiving party but maybe it'll  be too much?)
-  Unable to go to therapy appointment

Both were illuminating but really most of the cons are purely selfish and if I want to branch out away from where I'm working now, I need to do this at some point.  I feel like now is as good as any.  It's just all happening so incredibly quickly.
