We do not have to be ashamed of what we are. As sentient beings we have wonderful backgrounds. These backgrounds may not be particularly enlightened or peaceful or intelligent. Nevertheless, we have soil good enough to cultivate; we can plant anything in it.
Politeness is the first thing people lose once they get the power.
Growth is an unavoidable part of life. Whether we mean for it to happen or not, our bodies continually nourish and regenerate themselves, our minds continually learn and expand, and our lives continually evolve. We have the power to craft our growth the way a landscaper crafts a majestic garden, or we can leave it to chance, allowing it to unfold wild as the weeds that spread across a vacant lot.
Any relationship (friend, romantic or business) that's one sided isn't one; it's a one way street headed in one direction... nowhere. Cultivation requires input from willing participants.
