I have confused, swirling thoughts regarding this issue, as I have a DB pension, as well.
I've gone back-and-forth between feeling lucky, then cursed, then lucky, then cursed, then confused!
With my relatively "late start" regarding saving and my salary not being super high, I'm not sure I can afford to disregard it. But I just don't know, I feel more will become clear with time. Right now I am just focused on the FI portion of FIRE.
