Why wait?

Seems like everyone is always waiting for something;
we wait for the right time to tell someone something,
we wait for the right weather to wear a cute outfit,
we wait all winter for the summer to come again,
we wait all week for friday,
But why?

Why are we always waiting? When is really the perfect time?
What is the right weather? Why is summer so much better than winter? (besides the horrible snow, of course)

Things would be so much better if we didn't wait.

"It's a terrible thing, I think, in life to wait until you're ready. I have this feeling now that actually no one is ever ready to do anything. There is almost no such thing as ready. There is only now. And you may as well do it now. Generally speaking, now is as good a time as any.”
