I'd split my advice up:

Technicalities

• basically just read your posts above*, and/ or read the FAQs.

General blogging advice

• stick to a handful of themes
• write batches of posts at a time and interlink them
• don't worry about posting every day. Better to post three times a week posts which are quality, rather than churning posts out for the sake of it.
• have some integrity, post about what you know about!

Connect with other people

• start with Hive account@abh12345's* curation leagues (*no need to upvote every comment I mention you in btw, HONEST!) and the Hive account@minnowsupport project and take it from there.

Reality check about potential earnings

• Remember that most of the people who are earning $100s of dollars per post are buying votes, are early adopters or heavy investors.
• Aim instead to earn a decent second income, assume you won't ever reach those giddy heights!
• Enjoy the community aspect and forget about earnings may actually be a better approach.

Thanks for all the community related efforts btw!

*My advice to you is to offline those links, in a shared Google doc or something similar, so you can update them regularly, until steemit introduces 'pages' that aren't locked down after 7 days.
