To make sure you are pursuing the right first customers, it is important to study potential target markets to see which one meets the most of your ideal customer criteria and then validate the interest of these potential customers by talking to them and getting them to buy.
In addition to finding and selling to the right customers, time is your most valuable asset because you have a limited amount of money to cover your expenses and the longer it takes for you to generate enough sales to cover your expenses, the more likely you are to go out of business.
However, if you immediately, upon opening your business, make large recurring sales that cover your expenses with ideal target clients, time is no longer your enemy and you can take your time to make the right growth decisions without the clock running towards your bankruptcy.
