Just got off the phone with a friend who thinks she is not a good writer, even though she has completed two excellent articles in the last two days.
Here's the deal. Assuming you have basic writing skill, if you feel passionate about something you will write something raw and powerful. It will be good.
If you feel nothing about a subject but have basic writing skill (and intelligence), you will write something very clear. It will be good.
Both are good. Both are different types of good.
If you try to edit the passionate to make it more clear, you will ruin it.
If you try to edit the clarity to make it more passionate, you will ruin it.
Run with the type of good that you have.
