David Heine­meier Hansson:

Peo­ple who always work late makes the peo­ple who don’t feel inad­e­quate for mere­ly work­ing rea­son­able hours. That’ll lead to guilt, mis­ery, and poor morale. Worse, it’ll lead to ass-in-seat men­tal­i­ty where peo­ple will ​“stay late” out of oblig­a­tion, but not real­ly be productive. 

David wrote this in 2008, and it’s just as true today as it was then. I enjoy hav­ing a life, and I’ve loved work­ing for those who encour­age me to live it.
