We are on our own journey in spite of all relational companions we have with us. This sounds like an archaic thought, common knowledge I suppose. However, when the raw spirit of a certain truth springs in you, there comes attached a nutty nugget that pushes you to grow.
And in there spouts the niggling question: how much growth have I accomplished? The question doesn't bid the term - 'success' - which is trite, subjective and relevant to materialistic perceptions and prejudices. It is inner growth, a genuine by -your- guiding strength assessment of how much of life I have shaped to the degree that I can stand on my own influence.
How many thoughts are my thoughts, not mere parroting of others. How much brawn is of my own, not merely siphoned from another (which reduces one to a social parasitic crutch). How much of my laughter, smile, joy and happiness stems from my own storage of juice of goodness, not funneled from bleached circumstances and organized events.
And as Seneca has said, : "I will keep constant watch over myself and - most usefully - put each day up for review. For this is what makes us evil - that none of us looks back upon our own lives. We reflect upon only that which we are about to do. And yet our plans for the future descend from the past."
