You must know that Hakadosh Baruch Hu designated that you will be born specifically during the period in history in which you were born and with particular surroundings.  He decided who your parents would be for reasons that apply only to you.

He causes you to come in contact with various people some whom you should befriend and some whom you should distance yourself from. He also provided you with physical and spiritual strengths you will need to go through the path of life and contend with situations specific for you…

These are the best tools and means to achieve your purpose in life, the purpose for which you were sent to this world – to fulfill the will of the Almighty.  Here lies the source for your success. ~ R’ Shimshon Rafael Hirsch zt”l
