It is more important to persevere when you achieve something than to persevere when you fail.

Successful success does not depend on the strength, but on how long you can persist. Only by concentrating on learning can you get twice the result with half the effort.

As long as you work hard enough, an iron pestle can be ground into a needle. Only by focusing, focusing, and focusing again can an enterprise succeed. A gentleman's learning is important, and one must be clear, and if clear, one will have merit. Reading should be done with a long intention. Learning is highly specialized, while studying and learning is pure.

The human mind is amazing. As long as you focus on a certain cause, you will definitely achieve results that surprise you.

——Mark Twain
