Could you tell us a bit about yourself?
Born in Sydney Australia and grew up with a large family. Learnt a lot from family life and have worked in many positions with many small and blue chip companies. Studied marketing and advertising and have been working in the field for over 15 years. Currently owner and MD at Marketing Mechanics.

What motivated you to start your own agency?
I felt at 30 I’d achieved what I needed to working for others and felt I had a lot more I could do if I was to start my own agency and help other businesses. Plus I was never a fan of working in the big corporate world and complying!

What do you most enjoy about advertising?
The challenges that happen on a daily basis, the pressure of deadlines, the new technologies, working with teams to create something wonderful for a product or service and always seeing the end result.

What makes a good advertisement?
I’m more of a fan of “simple.” If the consumer “gets” the ad within the first few seconds it’s a great ad. For TV if you can understand an ad and what it’s about without the volume, the agency has done a good job. For print and other static advertising the points we look to always execute are:
– exciting the primary target market
– communicating the benefits of the product easily
– creating a “need” or “want” from the ad for the consumer to want to buy it or have it

I saw a really good ad just this week for a chocolate milkshake in carton. The billboard copy was: “Tastes Good. Buy some.” and an image of the pack. To me that’s what a good ad is all about. Sometimes the simple things are quite complex to create or sometimes they are simply forgotten.

What’s the most common misconception about being an advertiser?
That we get paid too much and don’t work hard!

What skills are most important for an advertiser?
– having life experience
– passion for the industry they are in
– being able to think outside the box
– being able to make a client brief into a reality and nailing it.

And last, how should one become a great advertiser?
I think to become a “great” anything takes years of practice, patience, persistence, making a lot of mistakes and learning from them, laughing and crying and having a lot of success. The only place success comes before work is in the dictionary, so with any industry, you have to put the hard yards in.

Try and learn from as many people you can, read as many books (and comics) as you can and surf the net any chance you get. Switching from job to job and industry to industry is great as well, don’t just settle where you are – always challenge you self!

Kunshan Diorama

Today, I’m visiting Zhengyi Old Street (正仪老街) in Kunshan — a city wedged in between Suzhou and Shanghai. This old street is like a leftover slice in between other parts properly planned by the city. On the horizon, I can see construction cranes, as if they are threatening the area; ‘we are coming to you […]

It’s 06:30 in the morning and I’m driving to the San Gabriel Mountains, north of Los Angeles. I’ve been trying to sleep after an exhausting week at CES, but I’m too excited for this hike and can’t wait to depart the Airbnb we’re in. Every visit to the United States is an adventure. The most […]

In Praise Of Writing (And the Case Against AI)

In Praise Of Writing (And the Case Against AI)

If George Orwell, one of the best essayists, were alive today, he’d be firmly against AI. Not because of 1984 or ‘Big Brother’, but because in ‘Why I Write’, he listed four motives for writing; Historical impulse Political purpose Aesthetic enthusiasm Egoism   Neither of these motives survives if you let AI do the writing […]

Secret Listening #6

Secret Listening #6

This series is called ‘Secret Listening’, from the Chinese word 偷听Tōutīng. I know this can be — and should probably be — translated as ‘eavesdropping’, but secret listening captures it better and adds a bit of jest. These little stories or remarks stood out to me, and show a more personal side of China away […]
