Positivity.
To live a positive life you need to have the right mindset. You need to allow goodness in your life. You can't surround yourself with negative people and things around you. You will not live a positive life with those people and things around. Surround yourself with positive people who can see beauty in others and things. People who can have fun and enjoy their time doing whatever it is that makes you all happy. I guarantee if you spend more time with good genuine people your life will look so much greater. When you spend so much time with negativity it makes your whole life that way eventually. Your personality changes like no tomorrow. You lose good friendships out of it. You are just so angry about everything thats wrong. You need to look at what is good and right in your life and around you. Sometimes people weigh you down and its hard getting back up. Sometimes terrible things happen to your life. You don't know where to turn. You should always turn to those who truly care for you. I promise their hearts are in the right place. Maybe not in the moment you see it but they care. You deserve a great life you can share with great people while laughing. Also you deserve so many wonderful memories. Try harder every day to be happy and look on the bright side of things. You will get there I believe in you.
