I'm taking my first economics class this semester. Based on what we've covered in class, I came up with this graph that explains why no one asks me to draw or write anything for them, despite my offer to do it for free.

1. The green line represents the quantity of commissions demanded from me. You'll notice that at any given price, the quantity demanded remains relatively low. We call this "inelastic demand".
2. The red line represents the quantity of commissions I can supply at any given price. You'll notice that even when prices remain low, I am still capable of producing large quantities of commissions. We call this "elastic supply".

Roughly translated, this graph illustrates the fact that I can't even give my own art away because no one wants it.
