They probably all said it ;) I'm familiar with them, too. Though Simon Sinek is probably the one who's been saying it loudest during the recent years ;)
Yes, I see Steemit as a business. The moment you join, you're an entrepreneur in a way (if you're not one already). Thanks, @tunnelrat! Nice to meet you! :)
Well met. :) I'll be looking for more of your posts in the future.
