Being able to work as part of a team is essential. You learn to give as well as receive support. I have learnt to be focused and I have carried this with me elsewhere in my life. I am also a safer driver and I am a stronger person mentally as I am constantly under pressure and have to deal with things.
I don't want to be just a voice on the phone. I have to get to know these guys face-to-face and develop a sincere relationship. That way, if we run into problems in a deal, it doesn't get adversarial. We trust each other and have the confidence we can work things out.
