It is my belief that while more knowledge can be debillitating more often than not it has a curative effect.
Trying to shut off “scary feelings” through raw determination is counter-productive. What is important is not the emotion, but what is causing that emotion.
If you merely hide from feelings the situation creating them is almost certainly going to get worse. All things of import are difficult to tackle, but that is why they are not trivial.
Seek first to understand, then to be understood.
