Really, you have probably too high standards on your writing. This kind of a writer's block typically comes from you trying to "write it really well" right away - typically with external audience in mind. Forget it. The best advice I ever got on this topic was: just write it down in plain language as it comes. Then, but only if needed, rewrite, rewrite, rewrite until it's better. But never aspire to write down well on the first attempt. You get only analysis paralysis.
