I've been at my current position for 11 months, and have been working on a pretty big project that I was hired to complete. I haven't made as much progress as expected by my bosses (for some good reasons). I have to present/demonstrate my work next month. I am not even sure I will have much to demonstrate.
I received an offer for another job and have 4 days to accept it. It is a great position and I think I am going to accept. My issue is that I feel bad about leaving my job toward the end of my current project, and about the fact that I haven't accomplished what was outlined for the project.
Is there anything I can do about this, and are there any circumstances under which I should not accept this job offer?
