When you're writing just to publish your thoughts, when you aren't forced to cover specific topics, when you're totally free about each post, it may happen often, that you start but also delete many drafts.
I often have ideas. Sometimes I think my ideas are great, so I start to write them down. But then I get interrupted or I rethink about my thoughts and come to the conclusion, that they aren't as good as I was thinking before.
Then I stop writing and usually let this draft in my draft list for a few days or weeks, maybe read it again, but finally decide to delete it. Poof. 300 or 400 words are gone. Several minutes of my life wasted. No, not wasted. I practiced writing and I practiced writing down my thoughts as words.
I think it's a very usual thing, to delete most of the drafts you start and just finish and publish the ones, you care about the most or that you like the most.
Many writing beginners have the fear of publishing stories to the internet. I can't really understand why, but I accept it. To those I give the tip not to delete too many drafts. Sure, some post really shouldn't go public, but don't delete your drafts, because you are scared about publishing it!
Look at me, I just published this post, that may seem useless to some, but I said to myself "Just do it!". Just publish that damn post! I liked writing it, so why shouldn't be there someone who likes reading it?
So far my friends, keep writing...
