Hi there @theessential! Thank you for dropping by. Thanks if you think I'm successful here but honestly there's a lot more who really gain here. However, for starters as what I did (base on my experience). Is to;

find your field/interest

Since your a "nurse" by profession and have medical background.. why not talk about it. create a video and talk a little bit about the stuff you did. talk basic medical topics, like first aid, how to's, what to do's... something like that.

Find your target audience

*TAGS helps you to gain audience. Left side of your screen are the list of the TAGS available and profitable (you can use/create any tags but those tags has insane audience).

*Everyday, interact with other authors by creating a conversational comments like this. If there's a topic that somehow related in one of your post, leave the link to there comment box. (Ex. Hi @theessential, I found your post very interesting and somehow relates to my own post. you may visit it and find the other side of it) {article, photos, videos, etc,.}

Invest to Bid Bots.

*Bid or upvote bots are very helpful both financially and audience. you can use this https://steembottracker.com/ and you can bid less 0.010 SBD and gain back around 2SBD it's not bad. the higher you bid the higher the profit is and since you're just starting with profit, they can really help.

somehow this is the basic of what I do at first... however, today, I'm more into bid bots since it really help do gain back profit. I hope you find it helpful but other than that I'm still learning the technical part here. :)

Good luck and God bless!
