Wisdom is the greatest return on time (‘ROT’) you can ever wish for BUT the latter spent without being ‘engaged’/’committed’ i.e. in so-called oblivion (You know what I mean: you are talking to someone, sometimes quite intensely, & when you say ‘So what do you think’, he/she responds with ‘Uh, just repeat that again/what were you saying’!?) is an utter & complete waste. It is a direct by-product of poor/lack of proper listening which is a skill in itself – the ‘I hear you’ is often a manifestation of listening but in fact NOT hearing i.e. the listener’s mind is elsewhere! Without proper listening, a skill you have to hone all the time, there is simply NO ROT!
