As a potential future researcher I would like to know how much I could focus on my research and how much distraction grants cause. My research interest lie in theoretical cs and logic, however the answers should include other areas so that they may be useful to other readers too.
Specifically, how many hours of your working day on average is dedicated to grant related issues - searching a grant, writing a grant proposal, writing the final report for the funded projects, etc.
I heard in an informal talk that this can be as much as half of the time of the researcher, say 5 hours, Monday to Friday. In such circumstance, I do not think I would be able to focus on the research.
