We can't solve problems by using the same kind of thinking we used when we created them(Albert Einstein). A butterfly flaps its wings, then two years later there is a typhoon halfway across the world (chaos theory).
We don't even know what happened to Lieserl Einstein, and you are claiming to know that her father definitely gave her up for adoption to "finish college". Not to mention she was born 1902 and last mentioned in 1903 after some talk of suffering from scarlet fever, and then Einstein had his son, which renders your bizarre theory of "adoption to finish college" highly improbable.
She might have been adopted, but most theories are that she died of scarlet fever, but the stupid reason you attribute to the slim possibility of adoption is completely your own fabrication.
i wouldn't want to be great.
"Great men are almost always bad men." Lord Baron Acton...
"Have you had the dream again? A black goat with seven eyes that watches from the outside."
That's a very broad topic. Great in whose eyes? God(s), parents, wife, kids, society, or yourself? Then what defines great? Simply being told, some preconceived notion, simple acts of kindness, a life of service, a rule of totalitarian authority, etc. Great could also pertain to an activity/skill such as sports and music where particular greatness is subjective and based on the eyes of the beholder.
I think if you live life trying to be great your missing the point.
