Yes, I agree with you. It's better to forget about your past because it already happens and you cannot change what you've lost. Focus on the future and see the reward will you get. The best is becoming so patience is what we need.
That's what humans should do, but if you just move on, it will be useless. It better to move on while doing it better than in the past, it's a good way of revenge. Just do more than was done in the past, because the most succesful people are feel the fail firstly.
