I can warmly recommend browsing through the resources that @thecryptofiend has put together at https://www.steemithelp.net.

If there is one recommendation that I can add, then it is to engage with the community as much as your time allows for. Take the time to manually upvote the content that appeals to you, start building your Home feed by following those authors that you perceive as valuable contributors and comment, comment, comment...:-)

All the best,
Shaka
