i met a peer play a guitar in a underpass today, which made me can not helping to ask him whether i can play his guitar for awhile. he agreed to and i started, however,i found i can not master flexibly like before.the fact reminded me the saying"practice makes perfect." some complex chord i can not play any  more becuase i did not touch it for a long time and my fingers became stiff.playing a guitar is my hobby and wonderful thing,definitely,it is right when you deep in some toubles which make you depress.the first way come to your mind maybe that you must go club with your friends for some drink like cocktail,whisky or Erguotou .but for me, playing a guitar is a more useful method instead, which can release my stress immediately. my mind and whole body immerse into the music so that the terrible feeling is already out of my air. i can get passion,energy from guitar, and i need to take account whether i should spend some time to practice more even if i am a busy man.
