the abyss of inquiries, quotes, and hoping for response

In the world of marketing for your own buisness i find it daunting at times and extremely rewarding at others.  Lately i feel like my inquiries go into a black hole.THE BLACK HOLE.............This black hole is kind of pretty. I might want to go in there and with my pillow pet, blanket, favorite book, and take a nap.......
Which leads me to think the following; 1. Are my products not interesting enough for a response?2. Did my email get into their spam?  3. Do i need to call them up?  i really hate doing that......4. What do i need to do to get attention?  i only have so many jokes in my aresenal of jokes.........5. do i just give up now?  And then i read the sign in the office that Mr. Know-it-All gave me.  Then.........someone emails me back! They love my product and want to work with me.  And i feel like Sally Field who just won the Oscar and she says; "You like me!! You really really like me!"  After all this emailing and following up it just might be worth it.......the marketing guru has rebooted herself!your custom cabinet girl
