What I found was that I could make decent money just by filling out online surveys for an hour or so, everyday. It was surprisingly easy since I could do them while chatting on Facebook or after my kids went to bed, so I figured I would give it a month and see how much I could earn. At the end of the month, I was so excited when my first check came in the mail for $638.28!
Become a dog walker if you live in an area where they are in demand. You can walk dogs for people who own dogs but who are too busy to walk them. However, this can be a demanding job, especially if you end up walking a few dogs at once or if you are walking dogs throughout the day, so ensure that you have the physical stamina for this type of job.
