I want all I want in life
What do you want in life?
I want a show that is suitable for children but also has adult jokes in it, I want to live my life as a troll on the internet without worrying about consequences, I want a friendship with a corpse, I want a civil war, I want a house made of cotton, I want a boyfriend who looks exactly like a girl and a girlfriend who looks exactly like a boy
You can dream all you want, but actually obtaining these desires would infringe on other people's lives, and some of them are impossible. Stop trying to focus on everything and just think about the things that you can work on and accomplish in your life.  Attaining some of your goals will feel even better than dreaming about all of them.
I want to focus on all these things but I keep getting bad grades, so I need to stop that shit and only focus on what's important.
Focusing on whats important to you will help you make actual progress towards those desires. Before you know it you will achieve successes in life.
