If you have too much pressure due to work or living condition

you should find a way to release it. One of an effective ways is bunching bags - go to any sports stores, you can buy a hanging bag $95, support frame $130 (if you'd like to put it in garage, you can hang it at garage ceiling so frame isn't needed), and a pair of boxing gloves $100 . Do it when you feel you are angry. Try it...
