Bit of text regarding rarity.

It's rare to have a good day. Because the definition of good will always vary from person to person.

By that same token, It's also rare to have a bad day. The definition is subjective, you know.

So... go out there and make a day for yourself. Good or bad, it's up to you.

I, personally, would encourage you to have a good day. If we're using a generally accepted definition of "good" (or the one in the dictionary).

In the end, the decision is yours. But please, drink plenty of water.
