When do we start? It should be before too long, before it's too late. Wake up, clear your space, stretch, meditate, touch the soil, open your heart and start the work that only you know how to do. It's time, don't be afraid, there is a life out there for you and though the years past have been jumbled and you did what you must, good or bad, sensible or not, it's not too late to do what your heart has always called you to do.
There are people waiting to help you, look around. They may only be there for an hour, a day, a year or maybe longer, but they are there. Find them or ... let them find you. All your experiences have brought you to now so start the work, it won't be easy, work never is but it can be glorious.
