I often think about Arthur Rubenstein, the phenom mid-century pianist, for whom a lot has been written about his mission in early life to "practice as little as possible." There's a lot of hyped up romanticism in these quotes and anyone who plays at his level has spent a lifetime playing piano, period. Regardless, his guidance about spontaneity, creativity, and the relationship to practicing too much, which I equate to the current discussion on overworking, is highly interesting. "I was born very, very lazy and I don't always practice very long, but I must say, in my defense, that it is not so good, in a musical way, to overpractice. When you do, the music seems to come out of your pocket. If you play with a feeling of 'Oh, I know this,' you play without that little drop of fresh blood that is necessary—and the audience feels it." Of his own practice methods, he said, "At every concert I leave a lot to the moment. I must have the unexpected, the unforeseen. I want to risk, to dare. I want to be surprised by what comes out. I want to enjoy it more than the audience. That way the music can bloom anew." Not all work benefits from risk, the drop of blood, the unexpected, that are all baked into the right amount of effort, but a great deal of valuable and innovative work does. |
Even the strongest advocates of "practice makes perfect" doctrines, such as Anders Ericsson, talk about something called deliberate practice, which is an expertly designed regiment, requiring exhausting mental and physical effort, the close tutelage of a veteran teacher, and adequate rest periods for its positive effects to properly ripen.
These authors typically assess that even a top motivated and well-rested individual can only engage in "deliberate practice" for 4 hours daily at the very most.
So if you want to do that, then far from almost doubling the length of your workday, you should actually cut it in half, and ensure plentiful rest and light recreation before and after your workday. Basically, mimic the way top athletes train.
Otherwise, don't delude yourself that you are "practicing" or "improving". You're simply working, chugging along sub-optimally, doing what you already know without substantial improvement or room to grow or learn much.
These very same authors predict that by working a punishing 10-12+ hour daily schedule, your skills will not improve, and likely will deteriorate, since you will become deeply disengaged (cf The Power of Full Engagement).
The idea that perpetually over-worked, over-stressed, nearly-exhausted engineers are "practicing" or "improving themselves" is a romantic wishful-thinking with no basis in reality or scientific research.
Anecdotally, I've seen such places up close. Most people there burn out and/or move on quite quickly. Turnover in these companies tends to be very high, and they only keep those who can't find a better job.
