Is considering your own mortality depressing or motivating?
Steve Jobs famously said in his 2005 commencement speech "... death is very likely the single best invention of Life. It is Life's change agent." and "Your time is limited, so don't waste it living someone else's life". I think about my remaining time a lot actually, so much so that I have a tattoo of a 'loading bar' on my wrist that represents 100 years, it's 1/3 full (I was 33 when I got it). I find considering my mortality extremely motivating but at time pretty sad. How do you deal with "Life's change agent" to stay motivated to make your dent in the universe?
