Hey there! Welcome to steemit!
Just concentrate on having fun and posting great content. Making money is a bonus, and it may take a while before this happens for you!
Do not beg others with comments on their posts to follow you. If someone thinks your content is great, they will follow!
Some basic rules would be: Do not plagiarise other people's content (and if you need to copy/paste a part of some article, always add a link to the source), try not to be rude, and if you ever need help, feel free to join the official steem chat at https://steemit.chat/
Enjoy your stay :)
