In my creative writing's class my teacher told us to write, obviously. But he pointed out that what we wrote about or how we wrote it had no meaning in this particular exercise. He asked us to put all the rules away for a while, also to not think about how we wrote nor what words and phrases we used. His intention for using this method was to eliminate all the boundaries, hate and criticism we put on ourselves and our writing.
Writing for three minutes straight feels like infinity when you don't have an actually idea about what you are going to write. "I don't know what to write.", was, for me, written several times before I finally stopped thinking about what letters I was typing. Something clicked, I started writing from my heart and mind, without all of that nasty criticism I always drowned myself in. From it came a mixture of beautiful content rapped around some nonsens with an emotional twist. I had explained the natural smell after a heavy rainfall.
I realized I have, way too often, criticized my writing way before I even start typing. To be honest, I am a perfectionist, however I now know that things, either it's writing, love or anything else in our lives, doesn't have to be perfect from the start. I am my biggest critic but that will never come in the way of the things I love again.
From this one exercise in school, I have learnt things about myself, my writing and life in it self. It all needs to be fun and not taken so seriously. If it isn't fun, there's no point in doing it.
