The first rule of job-hunting is not to quit until you've got your next position secured. Have you exhausted all options in your current job? You don't say where your unhappiness stems from. Is it interpersonal, lack of career advancement, boredom, abuse? Most likely your unhappiness is not a secret among your colleagues; be careful – if your quality of work suffers because of it you may be soon leaving the company on their terms, not yours.
