I think Vitamin J is a by product of the process of life. It isn't something we can "take" or have a goal to find. It's what happens naturally when we're mindful, positive, and above, all, grateful in all circumstances.
Sure, there are days when the "ribbons of chaos" are swirling around us, and we're not feeling as great as we'd like. The secret to turning it around is asking ourselves, "What's something positive and constructive I can do about this right now? What can I learn from this? What gratitude can I find in it?" There is ALWAYS something for which we can be grateful in every circumstance - even if it's only that we had the strength to survive.
