I learned way too late that I am procrastinating things that I already know, based on my experience, would take me forever to complete due to my perfectionism. And these don't necessarily have to be complicated tasks, but tasks that require choosing one option over the other, with several variables involved. The more I know, the older I get, the more experienced I become, the harder it is to make a good choice. It's a curse. But once I'd learned the emotional reason behind it, it has become much more manageable.
