My cousin was in town the other night and mentioned that he hadn't posted in a day or two. I told him to feel free to come up with something and I'd help. He googled something about boob cars since it's Cleavage Week. He found 3 pics quickly, and, from start to finish, had downloaded, uploaded, captioned, titled, tagged, and submitted all three. All in 20 minutes. Then repeated the process so he'd have something to post in a couple hours for the next day.
Inspiration is all around. The ability to use it, though, not everyone masters.
