If you can read and write English to around the Grade Ten [Australian] Highschool level, then there are some tools below you can start using today. They are designed to get you thinking outside of your comfort zone. Each starts with a story to demonstrate the topic, and follows with a worksheet. The last link will take you to a list of all Hobajing worksheets.
There is nothing to lose and so much to gain. If you have any questions, contact me [with the name of the worksheet] at email@example.com
