In how many days was Rome built? Not in a single day, that’s for sure. Ten thousand? Is Rome even finished? Probably not, so there is no right answer to that question.
When entrepreneurs struggle in a business, they persevere. Everybody knows Rome wasn’t built in a day, so they push through for many (consecutive) days.
Set goals with what you wish to achieve, and connect a maximum amount of days to the plans. You can always adjust as you go. It’s crucial to create perspective beyond “a single day.” Be specific in manifesting your goals.
