Although my primary concern is making sense of applied statistics in R language, as well as geostatistics; enough to make sound inferences / explanations in academics (public health, actually); I would be interested to hear how you tackle more challenging concepts are well.

Problems are usually,

• Video too long. Not understanding much.
• Writings too long and too confusing.
• Even after some time, I cannot write a discussion, or make a point in a discussion. (Forums and webinars.)
