Best times to work, rest and play?

The day is ideally suited to a work-rest-play schedule, even if a loose one!

And it's important the schedule suits us, not some external figure, such as a boss!

That is, we need to do things when it suits us, not someone else!

For me, the following day is rough guide of what works well:

9-2 for work,

2-4 rest.

6-9 play work on fun things.
