Leveled Up To 47 Today I'm Pumped

I'm pumped today guys, I finally leveled up to 47. I'm still kind of in the dark about what the criteria is for reaching each level. I've heard each additional level you climb is 30% higher than the previous but still kind of in the dark about what stats cause me to level up ie post count, upvotes, steem power, etc.

Either way though I'm pumped. Keep grinding guys the levels will come.
