Every time you get inside a car, you risk your life.
Now you do everything you can to avoid an accident. You spend time driving with a learners permit. You learn from an experienced driver. You take a test. You don't eat, drink, or put your contact lenses in while driving (I say it because I've seen it.)
But there's still a risk. A risk that someone out there isn't being as safe as you are. Actually, there's a very good chance they're not being as safe.
What can you do? You can drive. Because the amount of desire you have to get to another place is bigger than how costly the risk is.
And this is when fear does not have power. It's when you want/need something so bad that you're brain overrides (pun intended) the fear. In spite of the risk, you're going to do it.
Try to approach your life like driving: it's risky, but worth it.
