I've written about this before, but I think that every so often it's worth repeating.
About 40 years ago I read a book by an Historian called James David Barber. The book was called, if memory serves "The Presidential Character," and it broke down Presidential personality types into four categories.
I think we can make similar classifications of clients, agencies, even people.
Barber's categories were these:
1. Active-Positive. Energetic people doing generally good things.
2. Active-Negative. Energetic people doing generally bad things.
3. Passive-Positive. Lazy people who do generally good things.
4. Passive-Negative. Lazy people who suck.
In the best of all possible worlds you can surround yourself with Active-Positives. You have clients who do a lot of work and think big and want to be noticed.
In the worst of all worlds you find yourself amid Active-Negatives. Clients who like to scream at people with a shrill ad of the week.
When you're looking for work, or when you're working with a client, try to find Active-Positives. Try to migrate your clients to that category.
If you can't, get paid a lot of money.
If they won't pay you, leave.
