rant of the day language and thought

who decided what how and why we should structure our writing was it just a long process of trial and error and then someone decided that sounds good that is right who decided that they had the right to say that this is the way it will be done and anyone not doing it this way is wrong i want to use capitals and periods right now but im holding myself back in my head i dont use any capitals in my head i try not to even think in words but i cant without language can we think without structure can we create coherent ideas or explain them to other people what ever happened to actions speak louder than words what if they had thought of that earlier in the development of language would we have no language i dont know shit but im just throwing all this out there because it frustrates me that im stuck with the language i know and the way i can express myself its kind of suffocating because i know there is more i could be expressing i dont want to say saying because thats not what i want to do i guess art is more of the answer of expression i just need to find a what to do it myself
