This is absolutely absurd advice! It's spiritually unsound to ever think that getting something externally can make you happy. External things can bring comfort, pleasure and other temporary states. Happiness, like inner peace, can only ever come from within and one is delusional and chasing their tail to think otherwise.
The greatest life one can have is of service. Give joy, happiness, bliss, laughter, wisdom, prosperity, love & light to others. By doing so, you tap into the Infinite Source within ensuring that you will never have to do without these "treasures" yourself! ~ Lateef Warnick
