Getting caught in a rip current drowns people who swim straight back at the beach, and a post here explains what to do instead. It sits between a piece on email lists and a guide to setting up a business page on Facebook, and that combination is honestly what this blog is like.
Vadim Hrytsenko runs a video booth business for events, so several posts sell that directly, and you can read them as advertising for a service that drops guests into an instant music video. The rest is marketing advice from somebody who has to make it work for a real business rather than in theory.
The piece on buying email lists deserves your attention. He is blunt about what you actually receive for the money and about why the arithmetic never holds up.
His post on talent argues that a boy who became known for dancing was not so much gifted as visible, and that most of what looks like talent from outside is a hobby somebody simply kept doing.
Read the email list post before you buy anything at all.
