When you write a post that has over 500 words… the first thing you should do is to consider if you could make it shorter. Cut at least one hundred words if you can.
Make sure if you really need that introductory paragraph. If you really need to introduce one paragraph with another or if isn’t the whole text just an introduction to a conclusion, where in fact you doubt your own idea. If I’m talking about your text, that probably means you force yourself to write, so… stop it.
