I am 1,5 years into a break. Haven’t had time to feel bored yet. But I do look forward to a 9-5 job again, just for the structure it provides.

If you can afford it, why get back? Now after a dozen years I am bored of my 9-5 but running the race to make my FIRE numbers plus provide some cushion for my son with disabilities but if I had a choice I would quit again ( but I am much older now )
