Think of your favorite contractors, doctors, restaurants and so on.

So most agents are only putting about half of that $12k in their pocket, and out of that $6k they have to cover all of their operating expenses: licensing fees, MLS/ Realtor Association fees, continuing education classes to stay compliant with licensing requirements, monthly "desk" fees/ technology fees to their brokerage, health insurance for themselves and their family, errors and omissions insurance (required), marketing, car, car insurance, gas, clothes, computer/ software, cell phone, closing gifts, signs, photography, staging if they offer that, etc.

I think about how purchases affect my personal goals, our tenants, and people I buy gifts for. 

This is hands down, my favorite source for inspiration.
