I agree with this posts being unrealistic for many - the accounts you mentioned either came with a huge following, and or a huge investment, which brought the Whales to come and see.

I started with no following from elsewhere, and not knowing anyone on Steemit, so I think my case is more similar to the majority of joiners.

Regular content is a key to growth, a bit of luck, and plenty of work too!

Thank you for your kind comments! :)
