A day late and a dollar short?

The expression "a day late and a dollar short" simply means that something is both late and insufficient or inadequate, in other words it’s a way to describe a situation where an action or an effort is not only delayed in time but also lacks the necessary resources or quality to be effective. In fact, it’s “Too little, too late” backwards! 

This popular phrase is believed to have roots in African American Vernacular English (AAVE) and has gained popularity in the mid-20th century. Since the dollar had considerable purchasing power during that period in time, even a slight shortfall could have serious repercussions. 

The expression likely emerged as a poignant reflection of this era, emphasizing the importance of timely action and adequate resources. So, it’s better to write the important things you must do, down on yourr calendar, and be ready to offer something substantial enough when you feel compelled to do so. 

Anything past that prearranged time and its accompanying consideration, if it’s less than what’s expected, will make you look bad and will significantly aggravate your inexcusable time lag!
