Above I asserted an objective truth, and followed it with my list of subjective truths.
Objective truth: Sustainable happiness is recognizing what is truly valuable in life and appreciating it. To elaborate, to evaluate the value of everything in life based upon its monetary value would be a mistake and limiting.
Then came my list of subjective truths which I prefaced with "For me this is". By subjective I mean I acknowledge that while I hold these to be true, I am unable to prove to you that they are.
To address your points: I really need to get back to coding my startup. I will revisit this later. I hope that you continue to discuss this with me even though no one else will care by the time I get back to it. (From the HN community perspective this thread will be most likely dead before this evening)
