Marriage
russell: 50% of all US marriages end in divorce.  I would say it's partly the poor judgment of youth; mine wasn't so good.  Maybe it has always been true, but now it is easier to get out.  Romance is a pretty poor basis for a marriage.  With mutual respect comes love and a more lasting relationship.  Consider all the other qualities needed for success.Starting companies is a huge commitment and raising children is an unbelievable stress load.  The combination is a marriage killer.With all that said, a good mate is a good thing to have.
