Thank you for the complement. Finding your own voice can be tough. You did a good thing by starting out with technical writing because it at least got you started with writing. So many people feel that they can't find their voice so they simply don't write. As demonstrated by your experience, your voice will develop. All it takes is for you to start writing. The more you write, the faster and easier writing becomes. Eventually, your voice begins to shine through your writing.

You are right when it comes to getting them done and not stressing over perfection. One of the best pieces of writing advice I have ever come across is that "done is better than perfect". If it is done, people will read it. If you wait for it to be perfect, it will never be published.
