How did you teach millions with 153k subs? Almost always, sub counts are considerably higher than the number of people who've fully partaken, and even granting that in a field like yours, perhaps the number is higher, it still seems above the line of "HyperBole".

To say you've taught MILLIONS just seems like an unnecessary boast.

Your stuff actually looks quite good.

Maybe you could change the title to be more humble,
and it would be better.
