An overview
The root, the fifth [its fundamental harmony] - moving through the major third, a description of joy too pure to be real, the minor, a perilous alternation between beauty and pain. To describe love, freedom - is to balance between the two [the uncertainty, accommodating more elaborate interpretations of harmony, emotion]
To write - one must have the necessary skill/knowledge to express the depth of their emotion. Assistance, from like minded individuals can fast track this process - activating the neo-cortex, sustaining a sense of euphoria. It is an honest expression of one's ambitions, fears, loss, experience - success [a state of mind] is completely irrelevant, in this regard
Look at the root, the resulting chords - start from the sixth, raise the seventh [you're jumping between extremes]. Change the root to the fifth/fourth, notice the single note that changes - use these new notes to add complexity, shifting. Let emotion guide you from this point on - express yourself through music, using this base knowledge to understand the way you feel from a theoretical perspective. To understand your emotions is to gain control - with a stable foundation, a person is free to take drastic steps [without unnecessary risk]
