Albert Einstein is my role model for life. I know that he has accomplish many tasks, hard tasks. I have also heard that he fail many things too. Could someone list a list of things that Einstein wanted to do, but didn't or couldn't do? Thanks

Hello survivorboi !

Albert Einstein never made an official list of things he (still) wanted to do.
We know that he failed to find and complete the Grand Unified Theory :
The relation and unification of the 4 natural forces : gravity, strong nuclear, electromagnetic, and weak nuclear force - LINK (http://www.abarim-publications.com/StandardModel.html).

Einstein spent much of his life eschewing the recent (at the time) discovery of quantum mechanics, stating famously that "God does not play dice".

He was wrong.

He spent much of his life trying to create a grand unified field theory, unifying his special and general relativity with ways to describe the strong and weak forces, but due to his disbelief in quantum theory, it would have never worked.
