There is the possibility of two more games for the talismanic centre, with another final waiting if his Leinster side should see off Ulster in their play-off semi-final next week.
And having experienced his fair share of heartache as well as success, O'Driscoll insists it would be great to retire without regret being fresh in his mind.
"You are never satisfied, you always want more and want to win every trophy you are involved in," O'Driscoll told the Irish Mirror.
"You will always feel as though you could have won more. One thing is that when you get into a winning culture, it does make you selfish for more and more.
"You can't get enough of it and that is why now we need to go back to winning ways.
"The closer you get to the end, the harder those losses get because you realise you are running out of chances, particularly in those big games."
