To attain knowledge, add things every day.
To attain wisdom, remove things every day.
-- Lao Tzu
When we are reading to gain new information and learning to gain new knowledge, we are doing the adding task!
When we are exercising our thinking mind, we need to know how to untie things and remove the obstacles blocking our way!
Have great knowledge do not necessary make one a wise person.
To have wisdom, we need to unload the knowledge that burdening us and look at the core issue in life.
Study skills is to master the tools to access and accumulate knowledge. It may not help one to gain wisdom.
