"Do one thing every day that scares you"
Whether it's killing that HUGE black spider in the bathroom when your husband isn't there to kill it for you or taking on a big project at work; conquer something that scares you.
What do you have to lose? The answer is nothing.
What do you have to gain? Confidence. Self-esteem. A big ego. So the latter of the those three might not be good.
Maybe you'll enjoy yourself by completing challenges and pushing yourself.
Think of it as a mental workout. If you start conquering the things that scare you, both great and small, eventually you'll be fearless.
What fears have you conquered lately?
