Something that can help you at work and life in general as you improve your brain is note taking.
Most people get through school with late night cramming sessions in high school or college.
But a lot of this information is lost shortly after the project or exam.
Taking notes throughout actually builds knowledge (this is the whole theory behind math homework).
Applying this to work and life in general as you learn interesting or important things will help to build upon what you learn.
Cumulative learning is a function of learning a language, but it is useful in everything from taking notes during a meeting, to jotting down interesting things at home.
