I don't think this advice is generic - there can be different perspectives here.

In a managerial role in a large corpo, doing what could be crudely characterized as office politics, I often have this sort of FOMO - missing out on new initiatives, budgets and projects which would be good for the team; or being unable to prevent others dumping hot potatoes onto us; or just not knowing what is brewing behind the scenes within the company. To a degree, I have to do this so that the technical guys don't have to.

My job, really, is to be invited to as many meeting as I can. I can then ditch the ones I don't think would be useful. Of course, often I sit on meetings that are a complete waste of time - but that is an occupational risk. I don't find these frustrating - they allow me to relax a bit, do my email, learn more about people in the meeting, or just practice my note taking.
