No. 4: Taxi driver
Barry Korengold, a seasoned driver and president of the San Francisco Cab Drivers Association, says that in addition to driving skills, it takes serious zen to deal with the rude customers cabbies face every single day.
"We get a lot of disrespect, and then after a while that wears on you," he says. "People treat you like crap, so you have to defend yourself. You end up putting up this wall."
Cabbies have always had it tough. While the market is growing by 16 percent annually, the median pay is approximately $11 per hour, or less than $23,000 annually, according to the BLS. But that number dramatically changes depending on geography. Workdays are long -- sometimes 10 to 12 hours for full-timers, says Korengold -- and there's stiff competition with other drivers, though Korengold says he appreciates the job's flexibility.
Thanks to ride services like Uber and Lyft, competition is getting fiercer. Now that anyone can be a part-time driver, the job is increasingly difficult since these services aren't regulated in the same way taxis are, Korengold says.
"We're playing on a very unfair playing field right now," he says.
