face it, kids. there is almost zero loyalty out there from clients. if you have a client that is honestly collaborating with you, hold onto them. they're worth their weight in gold.
99% of my clients jump ship to just about any goober who walks int he door with a portfolio. it's been true since i started. they become infatuated with the power of creating cool design and then they start devouring everything they trip across like a kid in a candy store. the bigger a "business" they are, the less likely they will be honest and loyal to you - a mere cheapo designer (which they view as a low-level decoration process that can be dumped on a whim). no complaint, just truth (as i've experienced it over 35 years of doing this stuff).
like i said, if you get an honest collaborative relationship with a client - maintain it even to the point of self-sacrifice. it's too valuable to lose.
i often point out in my lectures about my own work that if you have no ideas whatsoever, use arrows. there's a category of solutions that can be applied to everything. that includes arrows, tikis, pretty girls (naked, especially), ashtrays, duct tape, hot rods, playing cards, old labels and packaging, and nuclear bombs.
wanna add more?
nice poster. good arrows use, too. i wish i did this.
