Stop whining that you don't have anything good to show in your portfolio. If you don't like what you have because the clients or counterparts that you've worked with have:
• no budget
• no sense of humor
• no vision
Then create your own, for literally anyone. (See the cluster of ads below - all spec - why should I care?) As a CD, it's nice to know that you've done outstanding work, for real clients with real budgets on the line.... but if you had 5 really good spec ads that shows me:
• how you think
• how creative your are
• how quick a reaction you can cause
Then most likely, you'll get the promotion, the job, the gig... or at the very least, my attention.
I've been known to pass on a talent, only to refer that person to someone I know.
