Whether you are ending the year with a new job or deciding to look for one in 2017, how you leave your current position can say a lot about you as a person.  It doesn't matter if you are leaving a job you hate or love, you must leave it professionally.  You never know who you will be working with in the future or if you will need a reference from a past company/supervisor.  Resigning the right way shows your integrity and reflects on how you might treat your new employer.  Little things can make or break your career and your reputation.
