Execution is the name of the game
First of all, thanks for giving us a reminder that it's OK if we don't have as many followers as the LinkedIn "Gurus" :)
As you mentioned, most of them are trying to selling something at the end of the day.
I do want to comment on the importance of having a plan, vs having a "good" plan.
I've seen a lot of marketers who are on the other end of the spectrum, which is just as bad.
They just execute a LOT - hoping something will stick, but ultimately weren't strategic in the planning stage.
The key is finding the balance :)
