The Three of Disks indicates a period in which you have been applying strong effort and attention into a project you care about deeply. This project is likely very ambitious, and requires much determination to push through and complete. You have been chipping away at it, maintaining your momentum throughout. This project may be taking all of your energy, perhaps at the detriment of other aspects of your life. Although sometimes we may need to do this in order to focus, we need to eventually develop a work-life balance to avoid burnout.
