There is nothing wrong with being prepared. In fact it is wise and prudent to do so.
However in my opinion you also have to understand both in your mind and heart that ultimately you are not in control. For some this is unraveling for others it is an understanding that they themselves are not in control of the universe.
Not being in control of all things and all situations makes a person dependent on their own faith and believes.
If you are an atheist I'm not sure what this means. If you believe in some high authority than yourself you probably have an opinion or feeling when it comes to good versus evil, what you think is right versus wrong, or what is moral and what is not etc.
Regardless, my point is no matter how prepared you are with stuff ultimately the biggest hurdle might not be having a physical item on hand that you need, but how your mind handles the situation you are in.
