Although I've not followed this series religiously, I must say this one is precise with beautiful messages...

Many people find it so difficult to teach people what they know for free...

Honestly, many of us are somewhat guilty of this 'crime', that we think mere helping someone with our knowledge can make such fellow outsmart us or steal our creativity. But I want to believe that this kind of thinking is relatively a primitive one and "greed-inspired". However, when we teach others (who have good intention) what we've learned, we ultimately gain mastery of what we have internalised, handled and utilised.

Thanks for sharing @oredebby.
kind regards.
