The big ad went up this morning. I only threw up once waiting for it (I think I have a cold or something TOO, but I'm pretty sure that was a stress-vomit.) It really shouldn't be scary at this point, considering how long I have been in business and how often I've done this, but I think since I'm having more "at what point is this business too much stress for not enough return" thoughts than before it feels like more is riding on it. But they said nice things, and there are nice comments, and I had two inquiries immediately (which has not happened before) so I am relieved.
I should run ads more often if only because all the "update this part of the website sometime" and "take more product photos" tasks get caught up on.
