Forget all the advice about the memory. It is all about the method.
If you write down the steps you do your work and compare that with other people, it's easy to figure out how to improve. But you can also do your own optimization. Once you realize the importance of a good method, the way to do things, you don't need much memory.
The Chinese classical book, Dao De Jing (literally the book of the Way), says "if you learn every day your knowledge/memory increases; but if you understand the law (Dao means the natural ways/laws of the universe), your knowledge decreases (but you can do more).
Every sentence in this book is this profound if you can understand. It also contains concrete advice on how to understand Dao. It is a philosophical book not a religious one (although many read it like a Bible). For those who suffer intellectually, this book is a savior.
What you say is true, but Russia can easily become an enemy of China.
Not as easy as you think. Russia needs money and China needs resource and has a lot of labor. China's strategy definitely is to transfer as much Russian technology as possible when Russia either has to abandon it or sell while it still can. Meanwhile American weapon makers are just hyping things up for whatever reason.
