We constantly interpret the signals we receive from our heart, our body, our mind, our spirit. Others constantly interpret the signals we send outward, mostly as result of observing our behaviors (ever so rarely, they hear our words, too). Interestingly, we are in control of both sets of signaling, because we choose how we focus our thinking/words/actions.
What we think about matters. Garbage in, garbage out. Efficacious in, efficacious out.
Misinterpretation is inevitable when the signals are mixed (either the ones received or the ones sent).
