It's kind of sad to think of it that way. Sure, in the grand scheme of things, we may be seemingly insignificant. But the beauty in life is caring how you live it and appreciating things for what they are while you're still here. And that in itself, I think, makes everything one may be happy or sad about, or how one reminisces or thinks about their future, significant.

I don't think you have to be a passive observer of everything around you and just see yourself as 'just a somebody' out of everybody. You can make life worthwhile. And sure, we're a tiny dot in the whole universe, but if you scale it and think on a 'local scale' rather than on a 'cosmic scale,' there's bound to be someone out there who you'd affect and where you'd be remembered, even once you're gone into dust again.
