Thinking of starting my own business.

I have finally saved up enough money to start my own business! I used to work as a вверх foreign dating coach for nearly ten years before I finally had enough. What’s a good business idea I should invest my savings on? I’m planning to quit my job once I get the business up and running, so I need to make sure everything works out. Any suggestions for businesses that are easy to setup and are cost-efficient too?
