To be or not to be afraid?

This morning I am thinking about fear. As I took my morning coffee and went on the terrace to enjoy it along with birds singing I poured it all over me as I thought that there was a mouse running close to me. There was no mouse I have to admit. But my fear for mice escalates in the speed of light. Sometimes I think that I should make use of it and maybe go to see some other planets as it feels like I can jump how high I want at those moments whenever I think there is a mouse nearby.

Psychologists use to say that we should get over our fears to make our life quality better. And maybe they are right. I have been trying to challenge and face my fears like hating driving to places I don´t know or the fear of hight but I don´t think that I will ever succeed in getting over my fear of mice. And at the same time I completely understand how ridiculous it is. Well, imagine, such a small, tiny creature. Quite cute after all. Yesterday when my cat had left another approval of his night adventures as he use to do after the first shock I actually felt sorry for the little mouse lying there. But whenever I have to face the situation the reaction is always the same.

So I wonder why do we have such fears that we understand are so silly? How many of them are we able to win? And do we really need to win all of them?
