I have just started with #3 by creating drone videos and posting on Youtube as well as DTube.

So far I haven't got any ad revenue from my first 6 videos. I hope that it will come soon by the time I am on my 20th video :)

And as you said, which I agree totally with you, Steemit is by far the most efficient way to earn. Either by consistent blogging till we get noticed or by investing and delegating SP.

Thanks for sharing :)
