What ws the easiest/ hardest for you when learning?

When I was a beginner splashing around, for me positioning on the board was the hardest part.
That took me ages to get right, but on the other hand, stuff like pop up just came natually, I never struggled with popping up at all.
Everyone's different so, when you were starting, what was the hardest/ easiest for you?
