Frustrating part of writing

The most frustrating part of writing for me is the punctuation and the correct spelling. I like to to write about a wide variety of things that come to my mind. When it comes down to adding my punctuation and spelling, I feel like I lose all train of thought and seems so time consuming, and, I feel like people criticize my writing for not being correctly written. I really just like my writing to flow and use whatever first comes to mind. I can address the problems in these areas, head on by going ahead and correcting my mistakes as I make them in using proper spelling and proper punctuation when need to be. When someone criticize my writing, not to get offended but take some of their advice. The main thing that I am learning is to relax and lose control, and to make writing fun and exciting.
