I like learning things, I like progressively getting better at things, I like helping people
A bit morbid, but a graph representing the number of weeks left in my life. The x-axis represents the week of a given year and the y-axis represents years. I've used 82 years, based on the Office of the Chief Actuary.
Every time I look at this graph, my heart pounds a little faster. Still, there's nothing like remembering one's mortality to get you to stop procrastining!
