Oh! Baby: When should you ditch diapers?

Diapers have never been one of my favorite parenting tasks--don't know many parents who savor it. And I've always been determined to have my kid out of diapers well before his third birthday. Is this possible? Will I psychologically scar my kid if I work to wean him off of diapers before he's ready? And can I get him interested sooner than he would have otherwise made the choice on his own? So far the reward systems seems to be working well, but what if he decides he doesn't like the reward anymore? Will my plan totally backfire?
