How to develop analytical skills?

One of the Good approach to develop analytical skills is that take any burning issue in the society which you can find handful. Start thinking about the different ideas that you'll get to reduce or remove them. The best example is sexual harassments. Try to get some idea on that then start thinking on the model that you get.. COLLECTION of topics that are useful for your model will determine your analytical power... I got an idea on how to overcome the sexual harassments.. listed topics that are useful to make that device.. there are many ways like others say puzzles,sudoku etc but this will be helpful to you and the society. If any ideas regarding any burning issues and boggling about how to implement please let me know.. Thank you
