I devoted my life to gain full control over emotions and switching states of mind whenever i want and eventually found a way to literally hack my dopamine system. This is pretty simple practice then can give you unlimited amount of energy and even cause euphoria if practiced too intensively.  I spent some time (around 20 years) using this practice time after time to see if there any drawbacks of living in high energy states and did not found them. In my 42 i have perfect health, look 10 years younger and have tremendous level of  energy and enthusiasm.  Now i am ready to share my proved and tested method of controlling and improving your state of mind.
