From talking to a lot of married couples it seems as if marriage takes a lot of work and a lot of self-sacrifice. Perhaps the maturity of age has something to do with the successful marriages being those that where entered into later.

-29 22.3%
-34 11.6%
-39% 6.5%
So if you are just playing the numbers, wait until your late 20's at least.But please, don't play the numbers. As someone already said, don't try to plan love.
I think it's kind of funny that we're all seeking statistics on marriage. Where are the romantics on HN?
At any rate, it's still the wrong game to play for the OP.
