It is true that growing our HIVE account involved all the 3cs you have mentioned.
Creating posts gives other users things to read about, and at the same learn and earn
It is a two-way thing
Once you create a good post, users read, and learn, and at the same time earn curation rewards when they vote on that post
At the same time, when you engage with other posts, you get the same thing... Lessons and curation rewards
Once everyone does this consistently, everyone gets to grow
Working together is always a win-win. Let us all grow consistently together.
