You shouldn't call them distractions, call them inspirations instead. The time taken to look at pretty girls is necessary in recharging your energy haha.
For me, I like to have a routine to make things quicker and easier. I think the way you are segmenting things is interesting, so I might try that out as well. As for the big rocks, I try to chip away at it if possible, and if the time allows. But if it is urgent, then I like to do it first.
#prettygirlinspirations A great idea!
Having some routine in one's required tasks helps make them more efficient I think, certainly more than approaching them randomly with no plan. I guess it depends on the tasks, but from a work perspective routine, systems and schedules tend to be more productive.
