To be fair, sometimes self-interest merely means bribing myself, like for instance with a new Macbook Pro in exchange for seeing a contract through to completion, or maybe an expensive bottle of whiskey.

The self-efficacy portion is harder, but most of the failure of procrastinators is due to the self-created problem of not having enough time. Fortunately, focusing on increasing self-efficacy leads one to start making progress right away (i.e., not procrastinating).

Have you ever tried increasing your self-efficacy (belief in your potential for success)?
