Professional women in the city have to battle against old boys' clubs, sugar daddies and nepotism

In her bestselling book, Facebook executive Sheryl Sandberg famously encourages women to Lean In. What she means is that females should not be passive at home or work. Instead, they should be proactively pushing for greater participation in corporate leadership roles. To that, I say: "You go, girl."

I am all for smashing the glass ceiling. As a woman on a mission with ambition, I am always confronting the old boys and their exclusive club. And I make no apologies about clawing my way ahead. When I tell my colleagues, "I want to be on top", they know better than to smirk or suggest an innuendo, as I have no qualms about eliminating my office competition with a timely sexual harassment lawsuit.

Sorry, boys - not only will I lean in, but I will also elbow you out of the way.

I like blazing a trail for workplace equality and corporate feminism. It's as empowering as a rock anthem - I am woman, hear me roar! I work hard for the money, and now sisters are doing it for themselves.

While I have great admiration for the women who are making a difference, the same can't be said for a few of the local society ladies who are passing themselves off as working icons. You know the ones - they boast about launching restaurants, beauty spas, fashion boutiques and model agencies, but in reality, their sugar daddies from the finance world are underwriting these vanity enterprises so they can call themselves businesswomen.

But do they really know anything about business? Do they even know how their store's cash register works? Can they understand a single line of the bookkeeping?

To be fair, it is as frivolous as their rich boyfriends "investing" in a hip bar or club simply so he can use it as his own private den of debauchery. In a year's time, when he realises how much money he has lost treating everyone to free Champagne, he'll write off the debt and try some other trendy venture, like a spin studio.

I know Oprah Winfrey always preaches about how women should be supporting women and the importance of sisterhood solidarity. But there are a few office witches - ones even more spoiled than me - who I can't stand. If I sound jealous, it's because I actually work hard, whereas their executive titles come from nepotism.

I believe nothing does more harm to the feminist cause than an overpromoted, unqualified ditz. They have so-called "business lunch meetings" that last so long, we don't see them again the rest of the day. They're also the ones who leave the office at 4.30pm twice a week to get started on their hair and styling for cocktail events.

It's just unprofessional. If I get invited to a 6pm fashion function, I still won't leave the office until at least 6.15pm.
