Regardless of how successful you are, you always make mistakes, and often they're errors in judgment. Missteps shape your character and are just as much a part of who you are as the successes. The important point is what you learn and how you recover from them.

These six faux pas helped shape me as a leader and moulded a set of values that I subsequently adhered to.

Being ill-prepared. In a previous article, I described how I responded to losing out on the race for president but still landed well. The mistake I made is that I didn't prepare well enough for the interview with the board. The area I screwed up was finance and I remember their body language as I answered their questions. Not good. I knew. I confronted future encounters differently.

Playing it tight. Holding stuff close to my chest. Not sharing. I was a marketing innovator; my organization continually came up with new programs but I didn't always share what we were doing with the executive team. I was criticized for the lack of communication by my peers through the 360 feedback process we used. I was blasted by them. They were right. And I listened. Things improved.

Talking without thinking. My boss made an executive appointment that I considered ridiculous and told him so. Brazen. Presumptuous. Risky. Stupid. I was surprised I wasn't fired on the spot.

Reduced networking. I didn't avail myself of all of the networking opportunities that were open to me. They could have consumed every non-office hour available. I viewed evening dinner events and hobnobbing affairs as a pain that robbed me of personal down time. I was extremely selective in the events I attended and had a robust network as a result. But it certainly could have been broader if I were an "event junkie" like others. Perhaps it was a career limiting factor but although my approach yielded a selective number of deep relationships, I may have benefited from a wider network of casual acquaintances.

Of course it is impossible to tell if any of these six choices limited my career, or whether it would have taken a different path. I spend little time thinking about what could have been, but perhaps if I had …
