Allocate an hour each day when you lock yourself away. Make sure it’s at a time when you are fresh and alert – not tired at the end of the day. Have someone take messages to avoid interruptions. People don’t mind as long as you ring them back within a reasonable time.
Make sure your team know this is your planning time and that they need to give you an hour alone. Keep in mind the “big picture” but break each planning day down into chunks so you look at one part of your business each day or over the week/fortnight.
