Be it theatre, work or otherwise, I have come to adopt a self-devised psychological approach to handle situations that sometimes arise when collaborating with people with different types of personalities. I call it ART.
1. Accept (people the way they are)
2. Respect (for what they bring to the table, for they always bring something you don't have)
3, Trust (that no one is out there to get you)

I believe in it. I practice it. I recommend it. 

It helps me through what could become sticky situations: a heated policy debate at work, an emotionally charged political dialogue with friends, an unimpressive service at a restaurant or a long-winded diatribe from my aunt about why guys should not cook.

It is not perfect, but it works. To be aware of inter-personal differences and self-awareness of my own personality has been a true lesson. One that I hope I never forget!
