Keep them coming! Your account seems new so welcome to the great community of steemit. Have one upvote on the house and know that the steemit community awaits!
As you only recently joined the steemit community it can be hard to recieve lots of steem power so my advice would be to give @MinnowPowerUp a go as you can earn up to 30% more steem power than just powering up! It's a subscription based daily upvote bot that draws its power from a delegation pool. I have also made this post where I explain my experience with the service in more depth and show how I earn over $1 a day in upvotes.
