Napoleon Hill wrote, “You cannot succeed in life by scattering your forces and trying to do a dozen things at the same time.” I agree with this, because it seems to be true.
Then again, there’s Ecclesiastes: “Divide your merchandise among seven or even eight investments, for you do not know what calamity may happen on earth. … Sow your seed in the morning, and do not stop working until the evening; for you do not know which activity will succeed—whether this one or that one, or whether both will prosper equally” Eccl 11.2, 6.
So which is it? Do we have two different principles at work here?
