You were born in a country where you have adequate natural resources is nothing to do with your effort and intelligence. It is purely your luck. 

The basic but the most important resource is water. Can you create any water source? Can you live without water? It is either free or less expensive for most of you. But, how many people suffer without water on a daily basis.They have to sometimes walk for miles to fetch water. Some people are even forced to drink dirty/ muddy water as they have no choice.

So, it is your luck and the luck only that you were born in a country where you have adquate water.

Is it  all your effort that you got perfect teachers? No. Basically you have no choice. You do not get a chance to choose your teachers especially during your childhood.

A perfect, helpful, kind, intelligent teacher is a blessing in your life time. They not only teach you lessons but also teach you good and bads. That's why in some cultures they say both your spouse and teacher are as per your fate.

So, getting a good techer is your luck and nothing but the luck. How many of you are lucky to have good teachers? Those who were lucky to have good teachers may not realise this fact. But, those who did not get good teachers, may always realise this fact.
