"Do not accept principal risk while investing short-term cash: the greedy effort to earn a few extra basis points of yield inevitably leads to the incurrence of greater risk, which increases the likelihood of losses and severe illiquidity at precisely the moment when cash is needed to cover expenses, to meet commitments, or to make compelling long-term investments."

Previous Quote

Now, it is sometimes said that medical care is too important to be left to the market, and that it is immoral to profit from the illnesses of others. I say medical care is too important to be left to the failed central plans of the political class. And as for profiting from providing medical care, we can never be reminded enough that in a free society, a profit is a signal that valuable services are being rendered to people on a voluntary basis.
