When we were little, we were always talking about growing up. As we've grown up, we just want to go back to being little. Well, we can't always get what we want. Growing up is inevitable. It happens to everyone. So if it's going to happen, embrace it. You're only as old as you feel.
If you're still in your 20s, you're still young. If you're still in your 30s your still young. Heck, even if you're on your 40s you're still young! While you're still young, travel. Travel as much as you can. Go near, go far, go see the world. If nothing's holding you back, then do it. Do it for yourself and experience things. There's a whole lot of world out there to see!
Try doing something new every day. Yes, lives get busy and finding something new to do every day isn't too easy, but at least make an effort. Even if it's just trying a new food, or running a few miles, or even watching a new Netflix series—try it. Make an effort. Get the experiences while you can!
Embrace being young because growing up is inevitable. It happens to everyone. At one point you will have to adult. You will have to fall into a routine. You will have to make a living. Spend money, have fun, love life to the fullest and do it while you're young. If nothing else, just enjoy. Enjoy being young, enjoy the small things, cherish the memories, and most importantly, live life.
