Study the habits of highly effective people. Do you know somebody who seems unplagued by akrasia?

Let's not forget that akrasia can manifest itself in "being busy in the wrong way", as opposed to just being lazy. The person may be occupied 20 hours a day working on something, but this doesn't necessarily mean that this something is their "best judgment".

A better idea would be to watch people who directly or indirectly declare their goals, then achieve them.
