Since the milk was flowing out,no matter how you regret and complant,you can by no means get back even one drop.If you had considered about it in advance,the bottle of milk might have been preserved.But now it's too late.What you can do is just to forget it and pay more attention to the next one.Saints are often confident,they never feel guilty and blame themselves because they have a strong sense of competition.As long as they have caught the chance even one out of million,they will persue success.
