Hi Dr Liza, welcome to steemit. Its an amazing platform to share your thoughts and knowledge and the most amazing thing about it is that you get paid for that.
But as a writer dont think about money while writing stuff. Write because its your passion. If you write with such intension you get content and the earnings becomes bonus. If you will write for money then at start as you commence writing your blogs, you will see you would be unable to attract audience, due to which you might get frustrated.
Best of luck. And if you have any interest in cryptocurrency you can follow me for the latest happenings in the world of cryptocurrency.
