Just finished listening to the Einstein audio book.
There were a few things that left me strong impression:

1. He was a good man, but flawed
2. He was a genius. But he didn't carry some of the relationships well
3. He was modest with the greatest discoveries in the 20th century. But
he told his son, he was just paying attention to some phenomena others were not
4. He related being a physicist to being a poet as both are with curiosity and intuition
5. He established his theory based on intuition
6. He believed that anything to be built right should be built simple(simplicity)
7. The story of his divorced wife taught me a great lesson.

Simplicity and intuition are two things I believe in.
Keeping curiosity shall be one of the secrets for a fun, interesting, not boring life.
This is the lesson I learned.
