In coaching professional women, I notice that it is often harder for women than men to make themselves and their achievements visible. Men seem to have no problem with telling people how great they are, but women shy away from this, feeling that they are being boastful or obnoxious. Talking about your achievements, and your team's progress in order to be visible is the surest way progress in a male dominated environment. Too often too we think it is enough if our boss and a few other colleagues know what we are up to – that that should be enough to get us to the next level. But bosses move on, lose favour themselves or in the case of several clients – get fired or die. Then who will be your advocate? What are you currently working on – and who needs to be aware of it? Once you think as wide-ranging as possible, it is easier to begin to crack that glass ceiling.
