Mondays are only bad if you think in "weekend" terms
start calling friday monday, and pick any other day to call saturday, try not to think in days at all, just go to sleep and wake up and call it anything....
Time is relative, so are the names we decide to give to groupings of time.
do what you want when you want ......
And if any job puts you down .... quit it
If you need the money that the job provides.... be happy you've got the job
If you still hate it .... do something else
If you think "how am I going to do anything else" .... you lack imagination
I love every minute my eyes are open, I like the time when they are closed too
