I so agree. Like you I’m new to writing, even though I have been scribbling stuff since I was a child. Last year I took an on line writing course and the one thing I learnt was that we can be over whelmed with advice and the ‘right way’ to write.
I too am not too bothered about finding an audience, although I accept if we have a gift of some sort, others might appreciate it. But I write because I have something to say or a story to tell. Once written, I’m on to my next one. Nice to get feedback and responses from where I publish my writing (my website, Medium and sometimes Twitter), but that is secondary to the joy of creating my written work.
I have no doubt that many writers will be glad you wrote this, me included.
