It's called investing in your self - no shame in that. When I first started I was apprehensive about doing it - but as my time here goes on I realise ( as you pointed out) it's not the same as liking your own posts on Facebook. That's our pre steemit conditioned minds talking. Keep upvoting your own stuff - now upvoting your own comments - when your vote is worth a shit load - and never voting on other peooles stuff is an issue I have - one user I've noticed - votes on content at 1% and then comments something irrelevant like "right" - which they upvote at 100% - netting them $.25 SBD every time - they do it at least 50x a day. I can't even flag them because their rep is higher than mine and they could tank me really quick.

Anywho - rant over. All the best.
