Why are you unhappy? - Wei Wu Wei

Why are you unhappy?

Because 99.9 per cent

Of everything you think,

And of everything you do,

Is for yourself -

And there isn't one.

 ~ Terence James Stannus Gray (14 September 1895 – 5 January 1986), better known by the pen name Wei Wu Wei, was a 20th-century Taoist philosopher and writer.
