Why are you attending meetings you don’t value or get anything out of?
If you don’t value it, if you don’t provide any value to it is it worth your time?
It’s not a bad thing to say you are not contributing to a meeting and leave?
That’s not being bad, that’s being upfront, and that’s showing that you care about your time and what you do.
Meetings don’t need 11 decision-makers in them, and yet they are always all there.
Pick your meetings of value and attend those ones, the rest, get your time back with and do something better.
