You do not have to post daily on LinkedIn in order to be successful on it.
But you do have to post consistently.
Consistently ≠ daily.
But consistently can equal daily, if that’s what you find that works for you.
Consistently can also be three times a week.
Or even once a week.
But you have to keep this going for weeks and months.
Find a posting schedule that works for you, then stick with it.
