@Greatest I am,
Once you've arrived at the hands of The Grim Reaper, and then been transported to the afterlife, you may find Heaven to be an absolutely amazing, delightful, groovy, like WOW MAN! place to spend your eternity. New activities all the time. Reunions with all your pals and loved ones of the time you spent on Earth or some other planet in some galaxy or place in the universe.
Never is it ever boring!
Of course, you may find your spirit/soul eternally residing in the other direction. Where Satan hangs out. Still, there's variety there too and the opportunity to reconnect with friends and family. (though a different group from the ones in Heaven)
Or, you might land in Purgatory. Now, that might be rough. However, you can exit from there by being either superbly good or horrifyingly bad.
