Choose your battles wisely. After all, life isn't measured by how many times you stood up to fight. It's not winning battles that makes you happy, but it's how many times you turned away and chose to look into a better direction. Life is too short to spend it on warring. Fight only the most, most, most important ones, let the rest go.
Today you had a very important lesson on taking punches. A lot of people will tell you that the first thing you have to learn is how to take a punch. But I believe the first thing you should know is that you can take one and survive. A punch won't kill you. Conquering your fear is the first step to becoming a powerful fighter.
Another of the hard things about being in a war, grandchildren, is that although there are times of quiet when the fighting has stopped, you know you will soon be fighting again. Those quiet times give you the chance to think about what has happened. Some of it you would rather not think about, as you remember the pain and the sorrow. You also have time to worry about what will happen when you go into battle again.
