I thought to pass on a recent paradox of mine. I am curious about your thoughts on this. I have spent most of my life really working towards goals that seek to improve the human condition. I realized one day that I am really living for the future and failing to appreciate the present. If I spend my entire life guessing at how best to contribute to the future of mankind, then what of the joy of living now? I had nearly lost this. I worried so long about the problems to be solved that I had forgotten why we should solve them. Is our greatest duty happiness, or contribution?
