For 20 years I worked conventional jobs - before that I went to conventional schools - and I hated Mondays in a conventional way. But since becoming self-employed, Monday-Tuesday is the equivalent of my weekend. Mind you, I enjoy my work and Saturday-Sundays in particular are a blast - so weekends aren't as enormously thrilling as they were in the old days.
Interestingly, Saturday is still probably my favorite day of the week. Before, it was because I was off, whereas now it's my busiest day for work.
And I enjoy work enough that I'm going to work today (Monday) - just because I feel like it.
But I ramble. My simple answer to the question, does anyone enjoy Mondays? would be:
Yep. Me.
