Christians, what is your idea of what we will be doing in heaven?

.. i get alot of answers to this from people i talk to of highly passive things like non-stop pious worship, floaty 'do nothing' mindless bliss type things, just hanging around in robes and singing ect .. this isnt how i see it and wonder how much of our activity there will be 'entertainment' and how much will be 'work' but what do you think?
