I've seen it mentioned many times about mankind being naturally lazy but still don't believe it. I think the problem is that we are too smart and require some motivation to get going. Once motivated or inspired we're willing to work especially if it's interesting and/or satisfying.The Annoyed Man wrote: Human beings are inherently lazy. Period. They only become industrious and productive if it beats the alternative.
Did you happen to see the recent Olympics?
I'm thinking of everyone I really know and cannot name anyone who I would call a lazy person. In my own case, I do procrastinate if something is boring but if it's interesting I work long and hard, sometimes only solving a problem with little or no reward. We have done a fair amount of volunteering.
Fun for us is seeing the grandkids, sailing, bicycling, or square dancing - all requiring considerable energy.
Inspiration or motivation is needed.
