You're free to be whoever and whatever you want to be and in most cases, being yourself here is just fine.
I'm offering you a link that includes some important account information.

You'll see two bars. One is a voting power bar and the other is a Resource Credits bar. Every vote you hand out will lower both the voting power and resource credits. Posts, comments, etc will also lower the Resource credits bar. They charge back up over time. If you run out of resource credits, you won't be able to post or vote until it recharges. As you find ways to earn money through posting and commenting, at first try to build up a healthy amount of Steem Power in your wallet. With that you'll gain more Resource Credits and be able to post and comment more. To speed things up, you could always buy STEEM and power it up, but it is possible to slowly build yourself up for free.
Good luck to you.
