By this point, you must have figured out that no one pays attention to meetings. Your goal is to be excellent at not paying attention by looking extra invested into the meeting. So what can you do other than all the other tricks listed - pull out a red pen and start circling/ cancelling random texts in the physical copy of the presentation in front of you.
You could be checking the ink of your pen, for all anyone knows, but by circling or marking with a red pen, you create the illusion that you actually deeply care about what is being presented and want to make it further better. YOU ARE WELCOME!
Alternatively, you could download the Nandoo app and get rewarded for all the walks you take and tell your team members how hoshiaar you actually are for getting rained in dope rewards just for walking! #shamelessplug #sorrynotsorry
