ESFP + ESFP

This can be very supportive, fun-loving match.

Being of the same temperament, in this case, has huge pluses.  Of all the types, ESFP's are one of the most generous with those they love.  They would enjoy each other's warmth and optimism; enjoying great conversations and their next spur-of-the-moment adventure. They're both quite entertaining to be around.

The foundation for the relationship is great - it is the outside world they must worry about.  Problems stem from the couple not tending to mundane affairs.  Both are too busy having fun to plan for their financial future.  One manifestation of this could be that ESFP couples incur a lot of late fees on their monthly bills simply because someone forgot to pay them on time. Other opportunities are missed (even the fun ones) by not committing to others or sticking to a plan. 

To be a successful couple, each needs to admit to their shortcomings and take steps to become more independent, stable, and structured.
