Investing conversations are full of stocks, markets and returns. Behind every price there is a company, and behind the company there are financial statements.
Buying a stock without reading them is like buying a house in a seismic zone without checking the foundations. Or agreeing on a price without noticing that a landfill was approved down the road.
Accounting won't tell you where the market goes next. Prices may follow a random walk, and no financial statement removes uncertainty. It does show what you are buying, what you are paying for it, and which risks sit outside the price you are looking at.
You don't need to be an accountant to invest. Double Entry Life starts from there: accounting as a way to read the financial reality behind the numbers.
