W?

Well there is a w.  Lets see W is for a list of words, another w, that may or may not be what you are looking for.
Wait, seems we are always waiting for something.  In an line up somewhere, waiting for someone to come so you can have the car when you have to be somewhere on time.
W is for today, Wednesday what is called hump day of the week.  Why? because it it the middle of the work week.  I'm coming up with a lot of w's aren't I?
Thought this would be a little harder than it is.
Another w is worthwhile.  You, I know I am worthwhile, I am worth my weight in gold, or is it now silver.  That would be a lot right now as I have to lose weight, which would bring my worth up not down.  I'm worthy of being loved, and being loving.
Tomorrow may be a little more difficult, X may be a one liner or one word.
