It is easy giving others advice, it’s easy to see where others could do it better, although only through our own lens and judgement of what better is and who’s to say what is the right or wrong way?
It’s a lot harder to take the medicine ourselves and in fact, it is not our business to advise others unless they ask for it.
It’s useful to have an answer in an exam or if you’re on a game show.
Other than that, it’s better to have more questions than answer.
Then it’s best for us to listen.
There is no shame in not knowing something. There is more shame in not bothering to find out what others know.
The more we ask the more we learn and learning and knowledge avoids judgements based on nothing much.
