May be you will encounter something which make you unhappy during your daily life,you maybe angery and mad with these trouble things,you would like to find sb/sth to yell at ,make a large sound or try to do something to abreact yourself.But why you do not try to think the trouble things on the bright side?Why not make yourself thik in the way as Chinese 阿Q think?
I am dare to say if you try think things always on the brigh side,you will make yourself happy soon and what important is that you will be cheerful and be kind and helpful to the people around you ,more love and less hate for everything and every person!
I always think things on the bright side , and I hope you can be beneficial from that way !
