Hi Rachel, welcome to SteemIt. Good luck on your Steem journey and I wish you the best. I've been here since 2016 but it was only last June when I fully committed to take Steem seriously. Please feel free to read my STEEMJOURNEY.

Here are also some tools that I use and I hope you can find them useful too:

1. Use Partiko App from your mobile phone to post to your blog, comment, and upvote content in SteemIt to earn points which you can use to boost your own content.
2. If you’re into games, you may wanna try playing Steem Monsters, a blockchain game based on Steem. It lets you compete with other players around the world with creature cards which you can sell and/or convert to crypto.
3. Get rewarded for staying fit and healthy with ActiFit - a Steem-based app which rewards you with tokens (which you can eventually use to boost your content) for being physically active. If you're already using Fitbit or a similar app, then you'll find this easy to use.
4. Invest your Steem Power at Smart Steem and get daily rewards and earn more Steem.
5. Earn rewards by sharing links to interesting webpages through DLike and earn Dlike tokens
6. Exchange votes with other users with SteemEngine.Net
7. Steempeak and eSteem both offer an intuitive way of using Steem, enhancing your user experience.
8. Earn free STEEM through The Crypto Faucet and Earn Crypto by completing tasks and watching videos

*Just a piece of advice too (as I see you made another post), don't use the tag INTRODUCEYOURSELF again and again as you may be flagged and downvoted. Since you already did your introduction, refrain from using that tag again in your future posts.
Cheers
Neil
