Is investment a balance between long-term and short-term, between oneself and the market, or between expectations and reality. From a micro perspective, investment is also a balance between data and perception, an absolute and relative balance. Of course, investment is still a balance between long and short positions, a balance between risk and return, and a balance between persistence and abandonment. Investment is a balanced art. Only by understanding balance and trade-offs can one be considered mature and not burdened by stubbornness.
