Thrift by Orison Swett Marden

The term thrift is not only properly applied to money matters, but to everything in life — the wise use of one’s time, the wise use of one’s ability, one’s energy, and this means prudent living, careful habits of life. Thrift is scientific management of one’s self, one’s time, one’s affairs, one’s money, the wisest pos- sible expenditure of what we have of all of life’s resources.
