If you ever think you had a bad day... Just think about Jack Bauer in 24 CTU. So many things can happen in 24 hours, right. Of course this is fiction, but what we live is always relative in a way.
We see situations and keep comparing them to other situations. "Yesterday was better, today was a succession of bad events... so : I had a bad day". Does this make your day a bad day? No, not necessarily. How we see things is probably more important than how they actually are. Sometimes positive thinking or creativity can transform a dark vision of a day or situation into a less desperate brighter vision. Knowing where you want / need to go is important as well. Targeting you out of the "bad day" also helps. As long as you can focus your thoughts out of it, you can escape having a bad day.
Like Steve McQueen in "The Great Escape", playing baseball while in prison. Is he thinking about the awful day he spent there? Nope! His thoughts are free already... and so is he.
By the way... I wish you all a delightful day! : )
