In our daily life, we are always guided by directions. The direction we follow has a great effect in shaping our lives. We tend to reach a certain range in fulfilling our ambitions. Just like in music, the direction, progression, shape or contour and range of a melody greatly affect the mood of a composition. Melody may go ascending or be stationary. It may move step-wise or skip-wise.
We always thought about life purpose, how to live it fully and how to keep ourselves from accomplishing it. It's easy to have our life spin out of balance before we realize it for many different reasons--including temporarily to achieve a specific goal or to simply catch up at times. Like a music composition, we have to strictly follow rhythm, even tempo, dynamics, correct phrasing. In life, we need to maintain a sense of balance.
