I am kind of doing the same thing right now.

I am only upvoting my blog posts and not my own comments. I still cringe sometimes whenever I see people replying to others blog posts and upvoting their own comments instead of the author. XD

Right now, the majority of my SP(not that much) is being delegated to communities I trust and have been proven to support quality content creators such as @qurator and @make-a-whale. I'm not gonna lie though that the daily upvotes I got from them is one of the reason why I also chose to delegate to them.

But as you said to survive in here you need to grow together with everyone else and not care about yourself only. :)

P.S: Nice to meet you! :)
