If you see eternity and all you can think is that it will suck just like your life sucks now, then you must live one boring and pointless life. With our limited lifespans and mortality, there are too many restrictions to what we can do, and also, limits to what we can get over as far as regrets, so I can't agree with PSJ. Imagine not having any of those limits, and the possibilities are vast. You could do and try anything and everything.
