Some female office workers are popular with colleagues, earning their superiors’ trust more easily because they keep a low profile though they are professionally sophisticated and tastefully polished, in sharp contrast to their flamboyant peers.
You might have better opinions than those of your colleagues that contain lots of flaws. However, proposing them straightly might cause discontentment of your colleagues with you being considered as someone who is keen on putting down others.
The virtue of low-profile women is that they would do the work others neglect while accomplishing their own work, leading others to have no doubt of their working ability and do not repulse them as an ambitious woman. It would also raise people’s expectations in them.
