Welcome to Steemit!

Hive account@iamstan gives good advice. Given your goals, consider giving the #informationwar tag a gander. Also, have a look at #introduceyourself, as that can give you ideas about how to best make a post doing so. A lot of bots and people troll that tag and it can be a rewarding post in both upvotes and finding interesting people to follow, as well as folks interested in following you.

Regarding humility, I reckon it's perhaps the most essential key to understanding, and particularly in science, as it's so easy to be blinded by one's brilliance when one has been continually reminded of it during the whole of one's education.

Thanks!
