You may not have your dream job, but that isn`t a valid excuse to perform your current job responsibilities poorly. Even if you aren`t totally fulfilled by what you`re doing, try to take pride in your work. At the very least, find a way to refrain from self-destructive behavior at least until you`re off the clock. It might be time to consider making a career change. Anything can look good on your resume if you phrase it correctly. Go for what you want and quit complaining about what you can`t change.
