Bank Lessons!
Don't just read. Read, then write about what you learned.
Create a topic, like: History, Self-Help, Psychology, Programming, Science, Literaure, Grammar or Geography.
Then add a new lesson and write about it. It could be from an article you read online, a book you read recently, or a class taught in school. The key is to write about what you learned as if you were teaching it to someone else.
So, instead of bookmarking an article you will never read again, save it to your Brain Bank account and write about it to reinforce your new knowledge.
