Would you like to tell me about the time where you thought later that you could have handled this situation differently with your colleague?

Here is the best example you can use to answer this question:
About a year ago I worked with one of my colleagues whose personality is different from mine. I was more competitive and a bit aggressive than he was, and always got irritated by his relaxed style of working. But what was shocking to me, that he was delivering more excellent results. That day I realized we need different personalities in the team and have to change our mindset and should be more open-minded.
