1: How to be stronger. Not only physically but mentally. All of the times we've had a family member pass away he would be the one to tell me " I know it is hard, but we need to be strong for mom," or the times I would come home crying because of a boy he would, number one want to murder them for making me cry, and number two tell me "Continue to walk through the halls with a smile on your face because then he will know he messed up," and all the other advice he has ever given me has just built me up and made me stronger as a person.
2: How to accept humility. There have been multiple occasions where, at the completely wrong time, he would bring up something embarrassing that I did. I just learned to laugh at myself and not take things so personal.
3: How to be a better person. I dont think he realized he was doing it, but he pushed me to be a better person and do better things for myself. Whether that was me watching him get in trouble for something and learning a lesson from it, or him always giving me those big pep talks. No matter what it was, he always pushed me to go above and beyond.
4: What I am worth. Sure your older brother can pick on you and insult you but as soon as a boy comes into your life he will automatically assume that boy is no good. He will not fear to tell you that he does not like that boy and that you deserve better. He wants whats best for you, so he will be extremely overprotective and have high standards for that boy.
5: What a true best friend is. In my life I've had a lot of "best friends" but he will always be my number one. When he and I have plans, he has never ditched me to go hang out with his friends. When I'm having a rough day, I know I can call him and rant to him about it. When I am at my lowest, he is always the one to pick me back up and push me to do better. No matter what he has never given up on me, and that is what a true best friend is.
We get into fights and are always at each others throats, but I wouldn't know where I would be today if I didn't have him in my life.
