I know that SP goes up every day by it's own... But, I don't care about it and I don't think about that at all...
As @newageinv said, the main thing is to NOT ALLOW that damn RC and VP percentage go over 95%... We have to keep it under that number... :)
So, create that ONE post (at least) daily, make few comments on your favorite post (like this one :) ) and upvote (and reward) posts and people that you love and that deliver some great contents which is interesting to you!
(and I'm saying that to myself also, when I have "those days" when it's tough to do anything)

And taking a break is OK thing... Re-start is hard, but if you pump yourself on the break, you can do even more after it!

Cheers!
