Yeah 15 million on a day is beyond crazy but it happened! But you get scared too, you hope it's not a one off, hope it won't go down too badly, etc. More pressure to deliver well on the next video(s) too
On the overhaul, I just decided that after 5 months of building a toy/play doh channel this will never take of enough to acceptable levels (too expensive to do well without sponsors) and despite how hard it was to trash all my hard work and money invested, I did it and went into skits which took more time to learn. I also changed from uploading daily/every second day to once a week to create more time for myself to learn how to be a better content creator. Otherwise you're just too busy creating junk without the time to learn/analyse and reflect. It was hard but it paid off for me.
