A person obsessed with the need to be happy will never be so. The obsession is the obstruction. He does not really seek happiness, rather he seeks for a condition which matches his personal idea regarding the nature of happiness. But happiness is not a mere idea, for one idea will always have competition from another idea. The is why the unhappy man chases for ever from one attraction to another. Happiness will come when he stops chasing, that is, when he stops thinking that an idea about happiness is the same as happiness. A man enjoying the sunshine does so without analysing it.
