Get out there in the Steemit community, make connections. Comment on people's blogs and engage, join Discords and make friends with people.
Another great way to make some Steem power is to take a small amount of Steem, say 3 or 4, and keep putting that into bidbots. Whenever you receive the payout for that post, start powering down your Steem power and you will have more Steem then you started with.
