Whether or not you follow the Getting Things Done approach to organising your life, sitting down every week with yourself for a personal review is a great idea.
If you can make it the same time and place every week you are more likely to make it a habit.
This is what I do every week.
1, At my desk - process my inbox to zero. File away reference. Add actions to my lists. Generally tidy up.
2, At my laptop - process my email to zero. Archive emails and add relevant ones to @Actions folder.
3, Empty my bag, my wallet and pockets of any bits of paper and sort out.
4, On my calendar - look back at the last 2 weeks and forwards for the following 2 weeks. Adding any actions to follow up on what happened or pre-empting future commitments.
5, Run through all my project and action lists and bring up to date. Noticing where I'm resisting certain things and reflecting on options.
6, Run through my short term goals and ensure my projects and actions are moving me towards them. Adjusting as required.
7, Doing any 2 minute actions that show up. Normally loads!
8, Capture any new ideas that arise through the review.
That's it. The more you do it the more you trust yourself.
And that's never a bad thing.
