It doesn't matter. As long as you have realized the mistake and try your best to correct it.  You still have chance to resolve it.

I never know the result. Sometimes we ignore some important facts. Just because we haven't recognize it deeply. We haven't realized it and spend time to research it.

Just according to your real situation to face it don't compel yourself to do some thing that you can't afford it.

As for a thing you have different ways to resolve it. So don't fix yourself in a circle.

Fighting. These words, please remember it in your heart forever.
