It would take more than a thousand years for me to get bored!
However, I don't think we have any idea what it would be like living forever.
Imagine a mountain of hard granite 10 miles high, every 1000 years a butterfly comes and brushes the top just once. This begins to erode the mountain and after unimaginable eons the mountain is worn down. Now, imagine you have been forced to monitor this event, not once but a million times. You haven't even scratched the surface of what it would be like to live forever.
You could rearrange every molecule in the galaxy in all possible combinations again and again and again and still not have started to live forever. Still think you wouldn't get bored?
