Economics and Philosophy
The laws apply everywhere:
Compound interest on business engagements means your business grows and grows, if you invest mindfully, regularly, more and earlier than anyone else.
Compound interest on marriage means your relationship gets better and better, if you invest mindfully, regularly, and especially when “the market” is contracting.
Compound interest on applied knowledge means you become wiser and wiser, if you study mindfully, applying your breakthroughs along the way.
Economics is philosophical. Are you investing wisely into all the areas of life that matter to you?
