How long does it take for EQ to work?

Could you elaborate on the time frame for EQ, or Emotional Quotient, to have a noticeable impact in a given context? Is there a general rule of thumb for the duration it takes to see results, or does it vary significantly depending on the individual's starting point, dedication, and the specific area of life they're applying it to? Additionally, are there any methods or strategies that can accelerate the process or make it more effective?
