When young, we tend to run away from things. Then later, when we feel stronger, we want to keep on fighting. There are times we need to turn away from things, this is not running away, but certain things aren't worth our energy. When giving energy, you're supposed to get filled, not emptied.
Turning away is not running away, it's simply putting a stop to a certain situation, keeping your own head up high.
Someone once said going away is giving in, surrendering to the people who try to put you down. Though my experience is when going away gives you more often than not, more opportunities. When people who cry you down see you don't need them to continue, who is on the losing end?
People underestimate themselves too often, I used to, yet again, experience has proven me I had more in me than the people were giving me credit for.
Quite often people take you for a fool. Remember:
The jester, fool at a King's court, was the one who could tell the truth and get away with it. It was the one who was taken for a fool, but it was the one who outsmarted everybody.
However, when people treat you as a fool, be the jester.
