Why on earth...
The simple truth about life is that it is all about perspective and we all see things differently, especially from our level of knowledge. What I may be seeing based on my exposure and experience, you may not see it. It can also be vive versa. A man specialized in a particular field will always have an edge than others who are jack of all trade.
Having said this, we are expected to tolerate one another and see things through the eyes of others because you might think it is easy when it is not. So, don't judge.
I have seen folks do exactly what they said they would never do, I guess they thought they were better until their situation proved them wrong. We cannot know everything, hence the need for patience and tolerance.
So, don't always try to understand why.
Why this?
Why that?
Too much details can take you where you do not want to go to.
Keep the understanding tight together.
Thank you for your time...

we must always understand the power of thought, perspective and challenging pre-conceived notions about life and reality
Eventually, we become our thoughts.
This makes it important to value our thoughts and channel it in the right direction.
