One of the most common New Year's resolutions is to lose weight. That means eating less and exercising more.
Since I'm all about synergies, I thought… how can you and I make a bit of spare cash from something we'll do anyway (i.e. exercise)?
Examples are all around me.
My hubby loves to play volleyball and being an alpha, he happily organizes volleyball leagues and tournaments. He rents the gym, buys or borrows the equipment, markets the events and collects money from the participants. He very often collects more than he needs to recoup the costs. Since my hubby does it for fun (and exercise), he returns the money (or has a party at the end or buys better prizes) but I bet a professional organizer could simply scoop the cash and nobody would mind.
Other ideas?
If you got really good, you could lead classes in whatever fitness activity you're interested in. One of my sisters taught aquafit for a while. She trimmed down her waistline and fattened up her bank account.
During high school, I'd walk dogs in the morning. That was a great workout, especially with the larger dogs (where they walked me instead of the other way around).
