Home-based activities may appeal for the chance they afford to unwind and let go. If issues have bugged you and left you feeling tired recently, then a retreat might do you a world of good. You'll need the peace and quiet because you'll be busy planning, discussing key issues, and negotiating terms for much of the week. The more rested you are, the more successful you can be. Think carefully about volunteering your time. It might be more trouble than it's worth.
