That’s right. Nothing is truly random. It always comes from something.
In any case, I am terrible at organizing my thoughts. With great practice, though, I have become a passable writer. I still often fail at being concise and to the point. Sometimes I will put together long strings of words that prove to be misleading. But I still write, because that’s the only way for me to get better at putting thoughts to words.
And this is why I still put down my “random thoughts,” because I get a lot of my better writing ideas from “random” sessions. Fact is, when we write, we are able to access parts of our consciousness that we don’t ordinarily access in our day-to-day lives. If something seems out of the blue when you write t sit back and try to understand where it came from. It did come from within you, somehow.
Spontaneity, too, is not random. It is purely acting on the impulses and thoughts that we all too often find we have to suppress. Some people can’t suppress them. Others choose not to. Even when I sit down to write myself, I still suppress some things, even when I know the writing is meant for my own eyes only.
So, when you write something “random,” it’s good to figure out, what made me write that? I wouldn’t stew over it. But it’s good to reflect. You may just learn something about yourself.
