should I start writeing my idea down more?

Should I write down my ideas and start to blog more?  I want to and don’t at the same time. I love how fluid my idea’s are and feel writing out my ideas could be a bad thing in a way. first is that it would burn my ideas into a harder neuro path or i would start my thinking off from where i left off in writing instead of thinking from scratch every-time. its like how you never take the back roads with the better view because there is a highway with a high speed limit. you miss the texture of a country side. I have a feeling that writing would turn my idea’s into that highway. some sort of neuro dogma not allowing me to turn my thinking on a dime. and if I still did, it would be a source of quote mining for people to say i was a Hippocrate when I had evolved and sincerely changed my idea’s due to new evidence.  But i need to improve my writing and communication skills and writing is the only thing i can think of to help that.
