Systems in Contrast to Goals

From Irresistible:

Systems stand in stark contrast to goals like “attract one thousands Instagram followers,” which serve only as signposts of failure. When you do reach your goal, a new one materializes in it’s place — now two thousand Instagram followers seems like an appropriate target.

Reading that this morning it’s making me think of my 1000 YouTube subscribers and question if that’s what I should be doing. Should I be working on developing a system to produce content I’m happy with instead?

As always there are no clear answers to questions like this, so I keep mulling it over.
