Curious question more than anything. I have a few including, but not limited to:
"I think I'm of **negative** benefit to my team and our work"
"This feedback means I'm doing a shit job"
"I've never done that before, so I should let someone else do it"
Idk, just thought I'd share some of the inner demons I battle on the daily :). As a reminder, be respectful to your fellow summoners y'all.
