not a good experience!

Hello, just a quick update. Feeling a bit let down this past 24 hours. An agent I work through led me to believe a client was about to buy four of my paintings - 99% certain - said the agent that the client would buy and just a question of signing on the dotted line. 24 hours later and I received the message, yes, you guessed it, that the sale had fallen through! Back to square one! I've been an artist for a number of years, and take this sort of thing on the chin. One just takes the disappointment, shake it off after a day or so, and return to the easel. But I'm not going to hide my disappointment. In truth, I needed the sales to pay everyday bills - Such as the television licence, which I'm being kept reminded is "overdue"! It gets dropped through the letter box with the "licence now overdue" message on the evelope seemingly increasing in size and alarm! And as for keeping petrol in the car - another financial juggling act. Why do we artists continue? Can anyone out there please tell me?
