How do you approach fear?

I have always been scared of spiders. So, when there is a spider on the wall, I do not like looking at it, but I have to kill it before it bites anyone. One time, there was a spider on the wall and I did not want to kill it, so my dad did it. Next time there was a spider, I had to kill it. It was very hard and scary to do this. I did this every once and a while. Eventually, I had killed many spiders and no longer hesitate at the site of a spider. I learned that it takes time, bravery, and persistence to overcome a fear.
