As a human, we tend to always have to make a decision throughout our life, even sometimes almost in every second of our life. A decision on what to wear, what to do, even the slightest thing, like how to breathe if we are still alive is part of our decision, conscious or unconscious decision.
And then often times we also have to choose things that have a big impact on our lives, which can change the course of our life. No matter which one you choose, our unconscious mind will always try to pick the best for our interest, but it is life that has the power to reveal the result of our choice.
Sometimes the result might be good, at other times it might be a bad one for us.
And I think it is also human for us if we tend to regret the decision that we made when the result is bad for us. Especially when we have time to be alone to reflect things that we have been done, and thing that we choose, and how it take a different turns on our life.
But we can always make a difference by taking a good lesson on the life decision that we take which somehow give us a bad result. With that then we can move on, and hopefully won't make the same mistake again in the future.
