Welcome to Steemit. And welcome to STEM.
I'll give you some advice, as "older" user:
- write only about the topics you are good at. If you do like that, you will be able to write fast, without efforts, with a lot of confidence and it will be fun to read because you are an expert in that particular field
- be original. If the reader wants to read Wiki - he will go to Wiki. This is a blogging platform and we want to see what You are doing
- never plagiarize. Seriously. Never. You can lose your credibility only once.
- write about something advanced, something I can't find elsewhere. There are muscles X, Y, Z in my arm. Ok... But that can be found in countless books. Explain to me how I can avoid injury, from the anatomical point of view and I'll be your follower. Forever.
