Peace

When you have exhausted all possibilities, remember this: you haven’t - Thomas Edison

While this is a perfect statement for some situations, it doesn't work for all. This can be a dead end for a lot of us. For some reason, we feel that if things aren't working out the way we want them to...we need to keep trying to force it to work. 

It takes wisdom and understanding to know when one more try is just what is needed and also to know when to walk away. 

Whatever the situation is, guide your decision by the peace you feel inside. If overall, you are at peace but a couple of areas need special attention; then another try is worth it. On the other hand, if it doesn't feel right, and you don't feel comfort; then it's time to move on.
