Not having air conditioning and sweating when there's 40 degrees Celsius is pretty unhappy moment. Not sure how he contradicted himself there. I can totally see where he is coming from. Having comfortable car, comfortable place to live can certainly give you long term happiness. I am sure in 20,30,40 years down the road if I won't have comfortable car and comfortable place to live I will be unhappy.

On that whole note. What is happiness? It's what we ourselves decide it to be. For me happiness is when I am content with myself.
