Friend, look online I to classical home school curriculums (curricula) and consider buying some of their books for yourself! Philosophy and the fall of great empires were key in good education at the time- which was majorlybdone at home until college. Many old books that the founders studied are even free on project gutenberg. The Law (Bastiat), Democracy in America (de Tocqueville) or any of the founders' original writings could be a great start also.

Fill your time and your brain with good and beautiful things, it is never too late.
