Good Post.
These two are some important take homes for me

Constant Learning
The other thing besides this focus on math and trading, his focus on reading 4-5 hours per day, which represents constant learning.

Evolve and Change
Warren started with a basic principles of buy low and sell high, as in buy “fair companies” at “wonderful prices” and he made a lot of money, for a long time. But he evolved away from that and started buying only companies he could be proud of, wonderful companies at cheap prices. This propelled him to even greater success and he credits this change for his greatest increase in wealth.

We need to be constantly learning and changing with our new knowledge.
Which is a good reason to read posts everyday.
Thanks
