One day, you're 19 and the boy you fell head over heels for in high school breaks your heart. One day, you're 25 and that boy that broke your heart is long gone and you don't even remember what his middle name is and he is just another name in the bunch of "should haves" and "could haves." But for now, be 19 and wear your heart on your sleeve for everyone to see. Give your number to strangers in the grocery store after you've talked about the weather and they asked how your Tuesday was. Forget what heartbreak feels like and remember the poetry you wrote with tears in your eyes. Wear a new shade of lipstick. Run in the morning. And remember these seven important things:

Life gets a lot easier once you realize that you can miss someone without wanting them back.

It never ends the way we think it should and sometimes you'll find yourself missing that person. Just because you miss them, does not mean that you want them back in your life the way that they were before.

One of the hardest things you will ever have to do, my dear, is grieve the loss of a person who is still alive.

I've lost friends in the process of figuring myself out. You'll lose a lot of people along the way, but those who stay are supposed to be there.

It eventually gets better, without any explanation, you’ll wake up one day and you won’t be as upset as you were the day before.

You'll know when the day has arrived, trust me.

You never think the last time is the last time. You think there will be more. You think that you’ll have forever but you never do.

Quit saying "tomorrow" and start now. Second chances don't always come around so act fast on everything that you've ever wanted.

A person that’s never experienced what I have experienced can never tell me how I should feel.

And vice versa. Stop telling people how they should be feeling and start listening. You can learn a lot about other people this way.

Be with someone that looks at you like they look at a menu.

All of your "annoying" habits aren't going to matter with the right person. The right person is going to cherish you just the way that you are. They won't want to change all of your quirks that make you...well, you. They're not going to be worried about what others are thinking about you and him. The right person isn't going to be looking at other people while you're the one that is holding his hand.

The past should stay in the past.

This one is important. It's in the past for a reason, little fighter. Keep it there.
