I don’t know...

There has been this thought in my mind for last couple of days, whether I’m too lite hearted & humous in my business interactions with internal and external business colleagues & associates. This thought has been echoing in my head since I had to facilitate a session to a bunch of people who were visiting the HQ for training workshop from overseas. My session was about an important operational subject, although it wasn’t related to neither regulatory nor safety. I wanted the audience to feel comfortable and be participative rather than me just talking. I wanted them to have a bit of laughter. I haven’t seen their end of training feedback though. But I think I did well in covering the subject matter.
Beside the above, in this past week, I also had to facilitate a bunch of meetings with business partners in the external company that I deal with and on reflection in one of those meetings as I observed the people attending looked a bit nervous about an important upcoming event, which I’m driving for smooth launch. I wanted them to believe we can do it and there isn’t anything to be fear of and I wanted them to feel comfortable to throw any of their doubts, questions, clarifications needed at me. So, I was a bit humorous to crack a few jokes - decent ones though.
I’m now thinking whether these people would take these things lite heartedly as I’m or will they think my behavior isn’t acceptable in a business settings. Should I change my approach the way in which I handle these things, but still try to maintain my true self !
