Give your best hours to your best work.
Map your energy first, then build the week around it, so the grant narrative stops landing at 4:30 p.m. when your brain is already mush.
Stop switching gears all day.
Batch the recurring stuff (one-on-ones, timesheets, desk schedules) into single blocks instead of letting them nibble at all five weekdays.
Get your life on the calendar first.
Block rest, meals, movement, and the people you love before work fills every open cell, because personal time that goes in last doesn't go in.
