I bought it, now I'm too scared to waste it

Sometimes I buy expensive materials that I'm then afraid to use. Here's what I've learned about that. Let that little piece of expensive or "precious" something-or-other sit for a while. Let it gather a little dust. If you wait long enough you'll realize that you wasted your money on it. At that point it's only right to use it with abandon. That's when the magic happens.
