The Secret to a Lifetime of Happiness. 

Fun. If you're not having any, why bother? With that in mind, here is my guide to having fun on a music festival vacation, even if it rains the entire time. 

Step 1: Empty everything from your tent. Try to re-organize everything into dry places, but avoid doing so when it's raining outside on all your stuff.

Step 2: Find the closest second hand shop. Matching jackets fix almost everything.

Step 3: When all of this fails, check into a hotel. Use someone else's credit card if possible, and make sure there is a pool. Once the pizza is delivered, your perspective will return.

Step 4: Call up some friends and go dancing. If you order enough drinks, you will forget you were ever cold and damp.
