"The doctor treats the patient while time heals the disease." (Voltaire) In this editorial, I first consider why psychologists need to renew their practice regularly and then relate how I recently applied this principle in my own career. I give reasons for my 'paradigm shift' and enquire whether we as psychologists are prepared to accept the challenge to renew our practice on a regular basis. I then discuss the contributions in this special issue consecutively under the headings listed in the table of contents. The editorial ends with a request to readers.
