Daily structure while out of work after 10 years as an office manager

I want a realistic schedule for the week that does not burn me out. Thank you in advance. I tried blocking out hours for applications but I lose steam by noon.

I aim for three focused hours, then stop. More than that and my applications got worse.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
