I'm now in my new job about 4 months.  This is the first full-time job I ever had and I'm quite unhappy with my job.  (working environment and the job scope).  I'm so unmotivated to learn new things given my current job.

I'm planning to look for a new job after new year but I'm told that the economic now is really bad and it's not easy to find a job now + terminating employment within probationary period looks bad in the resume. 

Anyone can give any suggestions on that?

cannot tell industry...the world is small...

I don't like the culture there and I don't feel like I can get along well with ppl there nor ppl like me.  (I might have serious personality problem.... )
How to transform myself from "little kid" thinking into "adult" corporate world? 

I'm getting uninterested in the work i'm working with.  This is basically a very desk-bound work and I don't feel like interested in the things of my company.
