1. Sharing is a must

And that means pretty much everything. Toys, clothes, makeup (when older), shoes, life advice, family, etc.

2. It's not just about you

There are still times where you may think it is but in reality there is another person that's constantly around you that also gets attention too.

3. At the end of the day, no matter what,  you still have each other

And you always will.

4. There's always someone in your corner

Always.

5. Family means the most

She's one of the few that understands howe crazy your family is.

6. Life is not always fair and that's ok

Having a sister teaches you that not everything is going to go your way.

7. Setting a good example is key

Usually, if you did something, she would follow, whether it was something in sports or artistic. Not that you minded much, most of the time.

8. You're a team

It's the two of you against the world.

9. Leadership

"You don't lead by pointing and telling people some place to go. You lead by going to that place and making a case." - Ken Kesey

10. Choosing your words when angry

Because you can't take words that you say back.

11. Compassion

Having a younger sister has taught me about a whole new level of love. She has taught me about how important it is to show her that I care.

12. How to be patient and understanding

Siblings can sometimes be a pain, especially when you don't want to be bothered but thats what makes them the best.

13. She'll do anything for you, no matter the distance and vice versa

She does it because she loves you and you love her.

14. They shape you into the person you become later on

Without them, you wouldn't be near as much of the caring and kind person you are today.

15. You're never alone

Literally, she's always around, not just physically but even when you're far away.

16. She's your best friend for life

And you're hers.
