I feel leaps and bounds this year, but the levels vary from experts still too far away. Look at the second ten thousand hours can not break through. To have self-discipline.
A daily average of 2000 hours, 40 hours a week, six hours a day self-study content of the red line can not be broken, (without work), specific implementation may work half + half of the learning content, or their centralized.
Last-ditch, and if not, is more age and ability does not match, that is, more dishes, preparing to retire completely.
