'Explain the change, the difference between What you want and what you need'

Today was a good day! My job has allowed me to rearrange my schedule to better fit around my art. I simply explained that I needed to take Friday off so that I could create at home alone all day without being interrupted and late into the night without having to worry about getting up early the next day. Fridays are typically a fairly busy day at work for me, so I was happily surprised that they would agree to the change. I feel that this is another big step for me. I finally have a full day allocated specifically for this dream of mine. Now I just have to make sure I get my ass in gear and don't slack off when no one is watching!
