Anyday, everyday, but mostly on the busy days, choose the meetings you ‘have’ to attend. Avoid the discussions where you have nothing to say.
Some of those events require you to be informed but not to actively participate. Some of them you were considered ‘just in case’, someone else from the team can cover you on those.
Check what your participation would be, the impact you’d have, or if you’d just need to ask for the end notes. Skip the sessions where you don’t have opinion nor action items to take care.
If there is nothing else to do but attend, take an extra cup of coffee, prepare your mind with your ‘Rocky’ song, put a smile on your face, a superman pose for your confident, and you’ll be fine.
