The quote “success is the best revenge” is often attributed to a variety of historical figures, including the Roman philosopher Seneca and the 19th-century American author and humorist Mark Twain. The phrase suggests that the best way to get back at those who have wronged you is to achieve great success, making them regret their actions and showing them that you have not been defeated.
The idea behind this quote is that revenge is a destructive emotion that can consume you and prevent you from moving on with your life. It is far better to focus on your own goals and ambitions and to let your success be the ultimate revenge against those who have wronged you.
