If you must say it perfectly, you will find it difficult to say anything.
If you fear mistakes, you will be reluctant to tap the "publish" icon.
If typographical errors cause you to tremble with humiliation, blogging may not be your forte.
These phobias can be overcome and you can emerge as a carefree, candid, and fallible blogger just like me - hopefully, much, much better, but assuredly, no worse.
In fact, you can emerge as a self-publishing machine with multiple "correctables."
This can happen if you will take this simple advice: WRITE SOMETHING!
You may not think you have anything about which to write. It doesn't matter.
You may not have the right words. No one cares. (Make them up if you must as I just did did with "correctables.")
You may not feel accomplished. Practice.
You may doubt that anyone wants to read you. Don't worry about it.
The ideas will come. The words will come. The people will come to read.
Lose the perfectionism and get on with it. If you have the itchy urge, follow it.
You can fix your mistakes later.
Be bold; be vulnerable; be free.
"Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest." - Eccleisastes 9:10
Again: If you have the itchy urge to write, follow it. You can fix your mistakes later. Don't leave a blank slate behind where your thoughts ought to have been engraved for the next generation. here are already far too many unwritten words in the cemetery.
