Don’t be bitter. Be the better half not be the bitter half. Learn that there are no problems too big to solve, just people too small to solve them if we just stop bitterness and attack the problem rather than one another. For example, it may be an insignificant small thing like a splinter. If you don’t bother to remove it right away, three days later you wake up with a throbbing pain, it's infected. Those little things that bring infection into your life. Banish bitterness. Don’t go to bed back to back, angry, don’t let the sun go down upon your wrath. Don’t be getting back at each another.
The key is understanding. No one is perfect, not even you. It's difficult enough to live with yourself, let alone another person for the rest of you life. I once asked an old married couple what their secret was. The husband said the wife was always right even if she's wrong. The wife said overlook the little things the husband does. Pick your battles. When you are really angry, let some steam off, then let it go. Pray and ask God to help you choose your words when you finally talk about it later. This won't be easy, because of our innate need to always be right. But, what's the alternative? What are the advantages? You decide.
Contrary to popular belief, the grass isn't greener on the other side of the fence. The grass is greener where you water it.
Till my next rant... LOVE ONE ANOTHER!
