The sense of the phrase “don’t look back” essentially means not to crib over whatever happened in the past and just move on. Moving on in life is essential and important. One will have to bear several hurdles and setbacks in life. The valiant and the brave lot of people always take lessons from their follies and make it a point to avoid making the same mistakes in the future. To err is human but to repeat that error is stupid. According to Jerry Bruckheimer, “Well, I don't look back and celebrate. I just always worry about the next one.” It is no good to cling to your past and keep on cribbing about them always. You have to look towards a brighter future. So it is extremely important that you let bygones be bygones and keep moving on in life. Past is history, future is a big mystery and present is the present or gift of life. So, never look back, always look forward. According to Satchel Paige, “Don't look back. Something might be gaining on you.”
