Balance in life and ministry is so important. It's not a myth, it's just seasonal. It looks different at different times of life and times of the year.
This is a nifty tool. Not sure if I will use it much yet but a lot of productivity people seem to really like it.
It is billed as a way to organize your life. I currently use Last Pass, Evernote, Google Drive, and GQueues for that purpose. I use Last Pass for secure things like passwords and codes; Evernote for a notes database (including sermon illustrations and journaling); Google Drive for docs, scans, writing drafts, preaching and teaching outlines, etc; and GQueues for tasks and projects. I don't currently use a Gantt or Mind Map tool because I found them more trouble to keep updated than they were worth for me. And I could accomplish most of the same things with other tools. I do value Mind Mapping for collaborative brainstorming but try to get the conclusions into a more useful linear format as quickly as possible.
