Here's a little piece on nostalgia:
Everyone says "time flies when you're having fun," but time flies no matter what you're doing. You know? Like, you may be sitting in math class, wondering whether or not it's been fifty minutes yet. It seems like it has, but it's only been twenty five. Yeah, time seems to slow down. But then that class ends, and you have five other classes, and before you know it school's out for the day, week, month, year, and then you've grown up and you're going to college and life stares you right in the eyes.
Life seems to pass by so quickly. I'm not sure if I'd say I'm nostalgic about fifth grade, but it just hit me that fifth grade is over. It was over six years ago, but it just hit me.
I think that's the key to being nostalgic. Let it hit, but let it hit much later. You don't want to end up unable to do anything else because you miss that one day in the forest, the time on the lake, the feeling you felt ten months, seven days, two hours, and forty-three minutes ago.
There's always a time for nostalgia; nostalgia in moderation. Like food. Because if you let nostalgia hit you as a giant tidal wave, you'll be stuck in the past and unable to be adventurous and daring and exciting and do the things that will probably make you more nostalgic in the future. I mean, be nostalgic. Everyone needs to splash in the waves of the past - ooooh, metaphors. Just don't drown, because before you know it, the sun is setting and everything starts over again.
