Feel like I'm Done

I don't know what's going on with me lately. All I know is that I don't feel like working here anymore. The bad part about it, it is not the people I work with but I do believe I'm just getting tired of the same old thing. I'm so ready to retire and start looking for a new civilian job. Not sure what I want to do but I am sure I want it to be my own business. Right now I'm taking Criminal Justice and hope to be finished by the time I do retire. Another reason I'm ready to get out is waiting on a promotion that right now seems impossible to get. So I would rather get out now and take my chances in the real world even though with everything going on might now find a good job.
