Today when we start business what we need? Certain amount of capital, manpower, resources and need to make marketing strategy for better growth. But 5 years ago Facebook ad was cheap, dropshipping wasn't popular that much; you had more nich product market + less competitors and better chance for growth. If we talk about decades ago there were no internet, no computer, no phones, no YouTube, no Facebook, no printing facilities and no e-commerce platforms still our forefathers were doing business with minimum investment of $50,000 and there were less chance of return investment. Today we have full resources for business and they didn't have 90% of resources + automation business. So when you want to start something DON'T GO FOR FANCY THINGS, JUST START WITH WHATEVER RESOURCES YOU HAVE.
