I think for writers, there is no such thing as "passive income". They have to keep on writing till they reach to the point where they write "harry potter" and sell that for royalty. I feel royalty and the staking, delegation seems to be the only passive thing and the income is not that big, just days go by with job like output from it.

For the rest, every large amount is in active income. There is literally no way out of this. You may find that there are people who make money off doing active work on anything that is lucrative in the trend. For some reason not everything can be turned into passive or automation either.

Trick is - just show up and keep moving as long as your hands and knees make you stand up.
