The most difficult / pivotal moment in my career occured shortly after Sheryl joined FB in 2008. She saw my potential and wanted to give me more responsibility for the business, but decided first to do a 360 performance review. The feedback from my team and peers was devastating.
I heard this from a co-worker: You are not "working from home", you are "at home during a crisis, trying to work". This is important to realize as even I'm struggling and have been working from home for years. 60% effort may be all you can muster.
