As a kid, we're always looking forward to the next big thing, like starting your first year in school, advancing to the second year, third year, etc., and finally high school, which is when you really start to learn. (or so we're told!) Then, when you're in high school, you start dreaming of university, having your own place, a partner, now that must be when life really starts, right? Gradually, you do work towards these things, and lo and behold, you're in university now.
Congrats! You may even get a place of your own, and find the love of your life, but of course, life doesn't start there now either, does it? First you have to graduate! So you work hard and learn, grow, find new friends, maybe lose that person who you thought was the love of your life, and gain another, but all the time, in the back of your head, life hasn't really begun yet.
Then, when you're working, finally, at this job you spent a lifetime educating yourself for. Has life begun? No, of course you don't feel that way. It might be that you want kids, or you haven't travelled yet, but whatever you think, there's some reason you justify to yourself that life hasn't begun yet. That it's just around the corner, but you just need to keep rushing forward until you reach it.
Life begins, when you first open your eyes, and take in the world around you. The first steps you take, which make your parents so happy. The first memories, which you'll treasure forever. Life has already begun, likely tens of years ago for you. You've just never stopped to think about it. No one day is more real than any other, or more or less part of your life. You're already here.
There's no need to think about what will happen in a month, a year, or a decennium. Try as you might, time will always pass. Life is as short as those winter breaks that feel like an eternity when you're in them, and minutes once they've passed. That sounds scary, but there's a remedy: Just make sure that every day, to know you are alive. Stop and smell the roses, take pictures of the things you like, document the things you do, and love to the full extent to your heart, past the point where it hurts.
That's how you live a life worth living.
