I don’t know, I don’t care, and it doesn’t make any difference!
Albert Einstein is my really favorite person. Everything that he had thought and everything that he had done, is the most powerful power moving our nowadays around. I have learned many things when read trough books about his bibliography. What i have seen are he was not rich, he was not smart but he had very high intensive to do something. With limited environment and conditions, however, he could formulate the (E=mc2) equation which was the largest change of our world. So, you do not need to worry if you do not have things what you need is “endeavors, try, and repeat”.
