For me I think it all revolves around the value we attribute to the past. To me, the past has little to no value. Since I can't change the past, the only thing I can do is learn from it what I haven't already learned, which is usually little. Dwelling on the past is useful as far as it provides me actionable advice for the present and the future. In reality, I often find myself thinking so little about the past that I have essentially forgotten large portions of my life.<p>Since I don't believe there is anything after death, this makes thinking about the life I lived useless, because in a short time, I will be dead. There's is no actions I can do anymore, so there's no point in trying learning from the past at that point. Perhaps thinking about the <i>good</i> things I have done will be worthwhile and ease my death. But I see no point in seeking regrets.<p>Of course I could also give advice to others on my deathbed. But it's something I try to avoid doing. On one hand, because I mostly reject the advice others give me, and thus I expect others to do the same, so I won't waste my time trying to give them advice. On the other hand, I generally find this advice either doesn't match my experience and world view, or it tends to be absolutist about the "one good way of living life", which I don't believe in. People all have different aims in life, and who I am to say which one is correct. Live your life as you see fit, I'm not advising you about what to do and what not to do, because I don't know you better than you do.<p>Something that annoys me a lot is when people say things like "do it now, or you'll regret it later". Even worse: "do it now, anything could happen in the future, you could get sick or even die". So what if that happens? If I die, there's absolutely no judgement I will be able to make of it, since I will be dead. If I get sick and become unable to do it... so what? I will be unable to do it, but since the past has no value to me, it doesn't make it different from anything else I was already unable to do.
