What is the origin of the idiom "take time by the forelock" and when to use it?

The idiom "take time by the forelock" has its origin in ancient Roman mythology. In Roman mythology, there was a figure named "Tempus" or "Opportunity," often depicted as a young man with wings on his feet and a forelock of hair on his forehead. The forelock represented the fleeting nature of time and opportunity. The phrase "take time by the forelock" is a direct reference to this depiction and reflects the idea of seizing opportunities before they pass by. It is often used in motivational or inspirational contexts to encourage individuals to be proactive and make the most of favorable circumstances.
