Aloha Sakke,
At your desk it's important to face one of your best directions, then a view of the entry, then being out of the entry flow.

If you received the Diamond edition of the course, you can fax/email in your layout and set up a 20-minute couaching voucher call with Wendy here at Learning Strategies.
Much Love, Shawn
