I work at beyond full time at a start-up cranking out code and putting out fires (~10am-7pm+). Then I come home and crank out more code on a project I'm working on (~7pm-1am+). There are just a ton of things to research/play nowadays. I feel like I'm constantly playing catch-up with things I need and want to know. Do people get to play with new tech at work? Should I be pushing for more hours to try something new at work?
