Forbes recently profiled the 400 wealthiest women in America. Although the number of women dropped from the previous year (48 to 47), this list is notably worth 8.5% more and includes many self-made billionaires. Elizabeth Holmes, who 'revolutionized blood test-technology', is the youngest self-made billionaire on the list, and serves as a great example for other young women looking to successfully start their own companies that ultimately better society. Glad to see Forbes profiling those women who are paving the way for future female entrepreneurs.
