Never make permanent decisions on temporary feelings.
To me this is one of the secrets of life. Don't burn bridges. Don't make permanent decisions when angry or frustrated. Try to make decisions that keep your options open, or will open up new options. Life is all about choices, the more you have, the easier it is to navigate.That being said, there will be times that hard choices have to be made regardless of the circumstances. And in my experence it gets both easier and harder as one grows older. Sigh.
