How can you live a happy life ?

People always tell me they are not happy about something they dont have or with people around them.
I always .. tell them that its not the people or the possesions you own that make you happy .. but the person
within you .
There is no way you can be happy with a million dollars if the person within you is depressed and complaining all the time.
You need to detox the inner you .. I know this sound a bit weird .. but just hang on !
Inner detox is just about refinding yourself. If you remember there was a time when you used to be happy and used to live life to the fullest ..go find that person .
Get into a fun filled active healthy lifestyle and do the things you love .. And please for god sake STOP thinking what others may think
