become more 'tough'

This one should be hard. I’m really a wuss and not afraid to admit it. I cry as a reflex to any pain, I’m too scared to try the big slopes on my skateboard, even though the falling I’ve done so far didn’t really hurt, I’m seriously afraid of spiders and heights, and I’m just a very weak person in general. This is a very vague goal, but I’m working on it. The whole becoming a skateboarder thing is helping a bit; I have to dare myself to do things I normally wouldn’t.
