It is no use crying over spilt milk.

Decisions write the future.

This saying makes me think of a teacher I had in 2013-14. She was the ugliest, meanest and most disrespectful woman I had ever seen. She was like the bad side of nanny McFee. She did not care about moralities or respect or children. All she cared about was to make children's life a hell, the money and the days off. She used to say this saying a lot, more than was needed.

To me, this saying means that you can't undo a decision you've made or an action you took. You can solve it by making other decisions or actions but you can't go back in time to make another decision, like you're in a game. Once you killed somebody, you can't turn him bak alive. That would be awesome though. So, think about the decisions you've made and the actions you've done and learn from them, that's all you can do really. This is one of the golden rules of life. Never, never, ignore the advice of someone but take it and think about it before you make your decision. This will definitely make life a bit more complex but that effort will be rewarded.
