I believe it´s very healthy to invest in yourself. So I do upvote my post 100%. I do not upvote my comments. I comment a lot and it would be a shame to not have anything left to vote with. I vote on every real comment I get. Meaning all that are not just nice post. For the comments I usually give 11%. I just like that numer and for the post I vote on I give more. Depending on the post.

Love your videos. :)
