It is very easy to exercise your brain with following steps:
Drink water very often:  Brain contains water 85% and its cells are like trees which need water.  If there is not water, tress will be wasted.  So you should prevent brain cells by usually drinking water, otherwise you might be slow thinking person or even have no idea on anything.

Enjoy good fat:  Less people know that brain is piece of fact requiring good fat to recover its damage.  You should have good fat during a day such as fish oil or cod-liver  oil, Ginkgo Biloba extract, salmon, soy milk, multi-vitamin and primrose oil to moisture brain cells. 

Vitamin C makes you feel fresh also.Meditation 12 mins a day:  After waking up, concentrate yourself for meditation 12 mins a day every morning to go through theta level which is most peaceful characteristic.  It gives you better imagery and creative thinking.  If you have no time in the morning, then you might do it before bedtime instead.Have specific intention:  To pay your attention on something is like to program target for your brain.  During a day, brain will adjust behavior to attain that goal because it does not separate what is real thing and what is human thinking.  So both of them are the same thing.
Often laugh and smile:  When you smile or laugh, our body produces “endorphin” which is a magical hormone to stimulate one to love and have good wishes to other persons.
Learn new things everyday:  New things here mean anything happen in daily life, for example, new restaurants, new friends, new books or new work approach of your friends.  To learn these new things influences brain to produce endorphin and dopamine which is useful for learning, arousing creativity and happiness.
Self-forgiveness everyday:  You should forgive yourself and others to reduce stress and brain energy.
Write graceful journal:  Try to write down good things happing everyday in your diary.  You might thank you for warm family, good health, happy job etc.  This will encourage brain to think positively and run good hormones that help you have nice dream, good concentration and creative ideas.
Take a deep breath:  Brain needs oxygen 20-25% of all oxygen flowing into body.  This practice is to deliver good energy to brain.  You should sit up straight to let oxygen come inside your body more or take a walk for a while during working to enlarge your lung and get oxygen 20% more.  Having bright brain can help you learn everything in this world, but your ability still depends on practice arrangement.  Let’s brighten up brain today for brighter quality of life.
