The answer changes depending on if I know when I'll die.

Currently, without future insight, I'm living like I'll die in my 60's. Live life slow, but not slow enough to let it run away, and enjoy the moment rather than thinking about the future too hard.

If I know when I'll die? I'm gonna live so fucking hard to do as much as I possibly can, make as big of an impression, and know when to disappear. Because, fear of death isn't something you should have normally unless you know you might die shortly. Otherwise, it's just a road that leads to nihilism and depression.

The real question is why the fuck are you so scared of dying without a reason to be scared? Just assume in your mind that you will live forever and that personal death isn't going to happen. It helps me move along.
