Ego Clash

Sometimes it is very hard to understand what runs deep in my mind. I knew what I was arguing doesn't make sense but still fought with my team members when it came to our release level testing. I couldn't comprise my thoughts and thinking. Later I calmed down myself and understood what I put forth was absolutely wrong from all angles. Not sure whether my headache, hunger or tension made me behave that way. Whatever I should have avoided such an egotistic act, it is important to think in terms of what is beneficial to the project and the team rather than my interest and convenience.
