Both writers make gobs of excellent points, and the discussion on both blogs and on Twitter is great. I agree with Dylan that there needs to be balance in life. Living a life that is solely focused on work, even if you're doing so in order to attain clearly defined goals, seems from my perspective to lack balance. There's so much else to do with our short time!
But I also agree with Joel that "Greatness comes from focus and hard work and making it happen" and with Rob Bronson that "Hustle is personal and whether you decide to hustle on a huge project or simply hustle yourself to bed every night is your business."
We may just be arguing over semantics, but I think http://improvehearingnaturally.com/Buy-Lasix.html it's ok to hustle, as long as hustle is measured by quality, not quantity. It doesn't matter how many hours you work. What really matters is whether those hours are used efficiently.
And actually, I prefer not measuring life in hours. I measure it in seconds because those are more tangible. Each of us has 86,400 seconds in a day. No matter how hard we think we're working, that number never changes.
The question is: What are you doing with this second, this moment? Whatever it is—writing software code, talking, listening, tweeting, walking, eating, breathing, reading this blog—do it fully. Be fully aware and present in this moment. That to me is hustle.
If you have 1800 seconds to spare, consider closing your eyes and listening to Still Life with Clocks, my musical commentary on this topic.
