I  am supporting @stevescoins comment here. Indeed if you put precious amounts of effort into creating an original and informative piece, you deserve to get maximum reward from it. 
For example this post appears well thought out and it actually provokes the mind. If you have the power why not use it on yourself too.
However, upvoting oneself in the comments, in my opinion, is not fair. The precious curation awards would be better spent on your followers who comment genuinely on your posts so as to help them grow.
After all that is the essence of a community.
