People think that they can not change the world. They don't even try to. Your mind is your biggest obstacle when it comes to achieving something.
The first thing that needs to be changed when it comes to doing something is your mentality. Simply believe in what you do and it will happen. How can miracles happen when you don't believe in miracles? How can you be pessimistic about something you do, but at the same time, you want it to end up positively? It just won't happen. BELIEVE IN EVERYTHING YOU DO. Even if it is the dumbest thing. When you fuck up just apologize. Is it that hard?
Don't just whine about how the world is fucked up and everything is working against you. Just take a deep breath, get your shits together, stop whining and start DOING something for God's sake. Don't listen to people who will say that you cannot do this or that. They are mean because they haven't done anything with their lives. Don't let them discourage you.
Don't let your mind stop you from even starting something. Don't be a prisoner of your mind. Don't let your thoughts control you. Break the invisible chains and CHANGE THE WORLD once and for all.
Nowadays more than ever we need to change the world for the greater good.
You are not alone in this act.
Have some faith.
God Bless.
