@greatpath,
Again you brought us a great quote. Yeah, anyone can complain. But how many of them knows the correct answer for his/her complain? If we ask this question when someone complain for something, we can reduce 80% of unnecessary complains in this world.
This is not just a quote, this is something we can use as a trick also :D Good quote for politicians :D
Anyway thank you very much for sharing such great quote with us! Really appreciate your effort!
Cheers~
Very well explained.
