Just like you said and I agree with you, we have results birthed from the zone of effort and results that are as a result of luck or by chance. This is actually deep specially for results we get by chance. I think it's something beyond the physical because how do we explain luck? If luck is by chance then how comes about the chance to get something effortlessly..
Well, that is some how far beyond my study..:)
Absolutely. That has left me thinking also and it just keeps me thinking more and more.
