Create quality engaging and original contents (write, music, video or anything), engage around with communities (discord, steemit.chat) and steemians from all around the world, collaborate and build up your own project on Steem blockchain is the best way to earn more STEEM or STEEM power!
Join competition is also another way too as a side post and you'll find lots of them in Steemit. Having the mindset of giving back to the community is also very important as Steemians do not like to just support people who do not contribute back.
Cheers 😁
