Charlie Munger offers some sage advice on multi-tasking:
I will say this, I know no wise person who doesn’t read a lot. I suspect that you can read on the computer now and get a lot of benefit out of it, but I doubt it will work as well as reading print worked for me.
I think people that multitask pay a huge price. They think they’re being extra productive, and I think they’re (out of their mind). I use the metaphor of the one-legged man in the ass-kicking contest.
I think when you multi-task so much, you don’t have time to think about anything deeply. You’re giving the world an advantage you shouldn’t do. Practically everybody is drifting into that mistake.
Concentrating hard on something that is important is … I can’t succeed at all without doing it. I did not succeed in life by intelligence. I succeeded because I have a long attention span.
