Tomorrow's another day. Some days you have bad ones and everything goes wrong.
In that case there's a lot to be said for writing the day off, giving up and going inside, putting your feet up and opening a can. Better that than struggling on, losing your temper and damaging something (or yourself) big time. Don't ask how I know...
You may find tomorrow that with a fresh pair of eyes/hands, you've loosened what you need to and it virtually falls apart.
