Look up Cal Newport's Deep Work book, he's writing one now Deep Life that you'll probably want to get as it will deal with this very subject.<p>The idea of working and playing at the same time is a bit fantastical. It's true you can flow, you can be creative, while working, but that's not play, and for probably >95% of workers, work won't be play. Work may be meaningful and purposeful, but really it pays the bills and provides meaning/purpose.<p>Play is something we associate with children and puppies/kittens, with games and sports and make-believe. Play is an enjoyable amusement which might mimics real-life tasks and skills in a safe environment. Work is real, and it isn't going to be low-pressure and fun for almost all jobs, otherwise why would they have to pay us to do it?<p>I'd look at finding true depth in the work you do, so you're finishing projects on-time, with high quality, in a non-distracted way that enhances your meaning/life. Then you use the ample spare time left to play.
