Your heart and your head...nostalgia is basically remembering and longing for a time where those two things were safe.
it's ****in bull**** mostly because safety is the illusion of idiots. That's why ignorance is bliss...That's why nostalgia is there to remind you to take it easy
I guess it's about taking the time to take some time out from bad sh*t.
That's why you have to work harder to not end up some nostalgic **** who's reflecting back and missing out on what's going on now. Cos if you get too focused on what makes nostalgia, you actually miss out on living the awesome moments, and a lot of things that are beautiful in their own way...
