How to fail at advertising 1

1. Assume you are not in advertising. It doesn't matter if you work in PR, digital marketing, content (ha ha), sponsorship or even 'native' you are in advertising, you are making every effort to get someone's product or service in front of people, to change their relationship with that product. You may be a goalkeeper, centre forward, midfield, sweeper or even manager, but you are still in football.
2. Assume you are an artist, a philosopher, anthropologist, comedian, behavioural psychologist or Stephen Speilberg. Depending on your job title, you might be a little of some of these, but the difference is, your job is to use these practices to sell things. it d
3. It doesn't matter if your five minute slow motion film of dancing mermaids recalls Fellini at his finest moment, if it doesn't get your client closer to a commercial result, you've wasted your client's money.
4. Rely on a process. There is a conspiracy among most large agencies of a variety of specialisms that a proprietary process will reliably produce outstanding work. All processes are variations on what everyone else does and only serve to make all the work variations on the theme too. It's about hard work, having an open mind and chipping away.
5. Believe you're better than the competition. Most agencies go to clients with the same sort of strategy and idea (see above). The trick is to make them want to buy yours because it feels different, or because they like you more.
6. Believe clients like you behaving like a dick. Some of the very best agencies still believe clients like them to be cool. Which is mostly true, since clients work in  proper offices doing a proper job, without pink cows in receptions and concrete tables. But, some of those agencies , who create brilliant work, believe being cool means being objectionable. Some clients will accept hateful treatment if the work delivers results, but will fire you as soon as you mess up  -and eventually you will. Lasting relationships are built on great work, but also mutual respect and even affection, even in these procurement led days, when you mess up, clients liking you means you get forgiven, for a while at least. It's the same working with other agencies, as soon as you make a mistake, if you've been horrific, they'll be happy to stab you in the back.
7. Not being nice. See point 6, but this applies to you personally and the people you work with and the people you work for. We've all worked with and for people who can work the system without being any good, or people who are good but treat the people around them like dirt. We've all worked in places where bullying, sexism and presenteeism are rife. These people eventually get found out. Once again, the job is too hard not to make a mistake, that's when you need people who have got your back, if not, expect a sharp knife between the shoulder blades. It's a small business, people talk, makes sure they say nice things.
