Flexible hours mixed with remote work are the top ones for me. I typically do my best work before I shower and get dressed for the day, or from 7-11pm at night. The hours when I would be required to be at an office (9-5) are literally a dead zone of productivity for me. I'm actually working at the office today and I haven't accomplished a single tangible thing due to interruptions, informal chats, and meetings. Between that and watching the nicest, sunniest hours of the day out of a small window, it's really killing my motivation.
