I am 22 years old, not married, and have no kids so it is not a big deal for me to sit on my sofa all day on a Sunday watching NFL football and stuffing envelopes. 

First, check every book for any money stuffed in between the pages.

If it's something you're going to do, I'd suggest only doing it for one round of a multi letter campaign.We're more than happy to do the stuffing along with custom crafting the letters and mailing them out for you.

I made gumbo, her husband made wings and stuffed potato skins, Daughter #2 made veggie pizza and chips and queso, Daughter #4 made croissants stuffed with mushrooms, Daughter #3 and her husband couldn't make it. 

Gone are the days of stuffing as many students as possible into a dorm.

@Mikhail Sazonov I actually did all the stuffing and stamping myself.

After several weeks it still smelled so bad my wife made me crawl up in the attic just to make sure they didn't have grandma stuffed up there too.  

Go to an REIA meeting locally, and tell everybody that you will do anything it takes to LEARN REAL ESTATE INVESTING, such as any job they don't want to do; for instance doorknocking, stuffing envelopes, putting up flyers, data entry, anything

Sell it and get something else that brings money in so you can grow.If you are in a stable job that you love and you are looking more towards retirement and you believe there is still plenty of "up" left in your market, then maybe stuffing $700/month into the property as an investment makes sense.I personally do not think it is a good idea to speculate on appreciation, but it can be very lucrative.

Good stuf @Linda Weygant.
