Seventy percent of businesses fail within two years.
Even if a business makes just enough money to cover costs but not enough to pay the owner a salary. Two years of not drawing a salary. Not many people have the savings to make it through one year without a salary.
Most businesses take three years to take off because they need that much time to have obtained the holy trinity of business where money for expenses, growth, and, income have been reached.
Gets old and tired fast working and not getting anything from it.
