Working On Three Products At-A-Time

Hi Brooke,

An Entrepreneurial question here – I would like to complete by the end of this year three products to launch/offer by January 2019:

Online Course

For each one there’s content to write for and some of the topics interrelate but some are separate.

When I tried the last two weeks to work everyday on all three by allocating 90 minutes or two hours to each, I felt a bit thrown off focus each time the blocked time has run out.
From your experience, should I allocate the entire day for each project on its own or even rather an entire month for a single product till full completion?
Have you ever worked on more than one product at a time?

Thank you!
