If blogging is something that you do, either as a hobby or why not? as a job. Then I'm sure you have a collection of drafts. Half baked ideas with tentative titles that seem to avoid ever becoming completed for one reason or another. Just like you, I often look at them, look at pictures to see if they inspire a cohesive closing, but still, they keep on piling up.
At this point there are probably hundreds, but honestly I've read them, and some don't work for me. Some of the "tricks" to get the idea to come out of one's brain lets say, seems so forced, so artificial, that I end up losing myself on the sentences.
In other words, the processes are so polished, I don't sound like me anymore and I can't get behind it, not really. I've taken this whole blogging thing as some sort of conversation with a good friend with you I share some similar interests. I tell him about cryptos, he doesn't really reply, but then again an archetype of the imaginary him shows up in the comments at times, and that is when I know I'm doing at least one thing right.
Without much work you can find tutorials, tips and tricks on this subject, on how to finish work, how to get over writer's block. But, again, those don't work for me, I tend to not fight it, just let go and write whatever I feel like talking about, very much like this blog.
Know thyself
Is the only true advice I can give anyone who has a bunch of drafts on a "virtual drawer". If you are writing about things you care little for, you are likely not to finish them. If you are writing while pretending to be someone else, idealistically that is, then you are likely to see them marinate towards irrelevance.
Best advice I can give anyone on this subject is this...
"just let go.. there's always something you truly wanna say"
