I think networking is one of the most important things here. Find people with the same interests as you, read their posts and leave insightful comments.
I think this is an article that is definitely worth reading:
How To Find Or Create Your Community On Steemit
Also, look out for communities and join them on Discord. There, you can get to know more people in the chat rooms.
Did you already create a Discord account? The truth is... you can't go without one.Most of the action is happening on Discord.
This server is a great place to get started: https://discord.gg/9qZy5SP
It lists a lot of different communities, and I'm sure they will be very helpful.
(You can read more about what the Discord channel is about in this post:
Steemexplorers Discord Unveiled - A Directory of Steem Communities and Services to Help All Steemit Users Grow.)
In the Steem Terminal server, they will also be able to give you some good tips. You can join them on Discord here: https://discord.gg/XZGPGpz
Another good way to get to know people and maybe get some extra earnings is to join challenges and contests. You can find them by searching the 'contest'-tag:
https://steemit.com/created/contest
You can use that link and replace the word 'contest' with any other tag to find posts about a certain topic you're interested in.
I'm a little short in time right now, so I'll have to leave you with this, for now.
I'll get back to you with more information. I've been planning to write a post with all this info, maybe I should finally get to work and actually write it.
