Unless you were blessed with thrifty parents, don't quit your day job until you've saved a fortune. You can save a fortune in a reasonable time. An investment left to compound will double in a certain length of time, its doubling time. It turns out that if you live on half your income and invest the other half, then in one doubling time you will have enough capital to provide you an income in pe rpetuity equal to what you were living on, i.e., you will have a fortune to provide you a living. Certainly, but it is possible, to you, and within about a decade or two.
Philosophy is a progressive science , like physics or mathematics.
It is not recognized as a progressive science because its progress has been imperceptibly slow. Its progress has been slow mostly because there were just too few deep thinkers to advance it. A man of 400 years ago would be astonished by the sheer numbers of scientists productively working today. It was Bacon who put them to work by observing that knowledge is power, and that nature is our ultimate source of knowledge. Philosophy is the most powerful knowledge, and reality is our ultimate source of philosophy.
