Start anywhere, any time. The path begins with the next step, in any direction. Just start walking with your eyes and ears open, being aware of everything. There is nothing more to enlightenment than realization, and there is always more to realize than we realize, so we are always being enlightened, we are always waking up, there is always more to know than we know. The Buddha died from eating bad pork! Shoulda seen that coming, Bro! There is always something else coming. Don't be thinking you've seen it all, or that you know it all. Always be listening, looking, being mindfully aware of everything. It is the way.
