30-year-old Brooklynite Christian makes a good salary: After taxes, he takes home around $3,500 a month. But even though he shares a three-bedroom apartment, contributing $1,300 toward rent and utilities, he can't quite make ends meet — because he's gotten in the habit of spending $1,100 a month on takeout food and more on subway cards and Uber rides, bar tabs, dates and so on.

Unfortunately, a Seamless addiction is only one of his problems.
