For some people, quite literally the only thing that will ever matter to them would be the pursuit of a greater amount of intellectual capacity in some way, shape or form. A big part of the reason why that is the case has to do with the fact that when you optimize your overall intellectual capacity you will essentially create a situation wherein virtually anything that you would want to start learning about would be well within your grasp in a way that would be utterly phenomenal for you if you think about it at any given point in time.
If you are the sort of person that conforms to this mode of thinking, you would not want to stop your brain training at any time at all even if you are on a party bus Dayton Ohio with all of your friends and loved ones. This is perfectly understandable, but you should at least try to figure out a way in which you can train your brain in a manner that is relatively enjoyable if nothing else.
A really great way for you to go about improving your mental capacity whilst simultaneously not bringing anyone else on your party bus down would be to start playing Sudoku. This is a game that originated in Japan, and it has taken the world by storm. Suffice it to say that playing Sudoku will more than likely give your brain the kind of workout that you want to offer to it, and eventually it will start to become so strong that you will become among the most intelligent people in the world and IQ tests will say the same as well.
