It&#x27;s generally the case that you can&#x27;t work on anything truly interesting or challenging until after 6pm anyway -9-5 gets chewed up so badly by all the bullshit, meetings, email, and noisy salespeople yelling into their phones, that the real work can&#x27;t get done until everybody goes home and some peace and quiet can be obtained.<p>3 hours of focused work with no distractions is worth at least 3 typical work days.
