Maybe you lose your cool only every now and again. 

But do you find that it happens at the most inopportune times?  Been there. 

Did at least one of those times cause a colleague, friend, partner to lose respect for you? Yep, I’ve been there too. 

I’ve had some serious crash and burns.  Being a manager in my twenties led to some uncomfortable situations with more experienced and/or older direct reports.  I tried to be tough and rise above but was not always successful.
