Pardon me sometimes I talk in very shorthand speak for the web -- I mean to say that everyone's day can be sliced into various segments, for me my "brightest slice" is typically a 4-6 hour interval that occurs shortly after I wake up, but sometimes I get into it later in the day. If you can use this "brightest slice" for your own company, or solo projects, those can become a passive income stream eventually. Lots of work does not require my "brightest slice" so I allocate accordingly.
