A Californian millionaire decided to reenter the workforce after retiring at age 27.
According to Daily Mail, Jon Carder dropped out of San Diego's Point Loma Nazarene University during his sophomore year after launching an online baby product retailer.
He sold the website for a couple thousand dollars to begin a new Internet venture, Client Shop.
The service matched users with the best possible home loans and low-interest rates.
Client Shop soon employed over 100 employees, and by March 2006, it was pulling in $8.4 million in revenue.
Carder sold the company for over $10 million in the same year.
He has no shame in admitting he started his businesses purely to get rich, and that's why he deemed himself "done" after selling Client Shop.
Carder celebrated his retirement with a surfing trip in Indonesia with 10 friends.
Carder wasn't worried when everyone went back to their jobs since he was set on traveling the world and seeing his friends when they were available.
But, it only took a few days alone on an Indonesian island for the retiree's satisfaction to completely evaporate.
He was "bored," adding,
He staged his comeback three weeks after retiring.
The plan was to create a website that used customers' recommendations of local businesses. Little did he know Yelp laid claim to this service two years prior.
So, he quashed that idea and moved on to restaurant rewards.
He created Mogl, which lets users ditch vouchers and coupons in exchange for digital rewards at thousands of restaurants.
He launched the app in 2010 and continues to run it with Jarrod Cuzens and Jeff Federman.
