Rand Fishkin from Moz suggests, in a video, invest in non-measurable, serendipitous marketing. I’ve done this quite a lot in the past years.
The trouble is I’ve done more than the suggested 20% of my time on this, and now I face a situation in which I have hobbies which account for more time than my actual work. Not so good.
From Nicolae Steinhardt’s point-of-view, this might be not as bad (see Saint Anton of Padua quote), but, still, it’s not so good, either.
So, less hobbies, more work.
