Bad Advice about Taxes

So I had this illusration/graphic design instructor that said, "Oh you can deduct photoshop and illustrator from your taxes."... "Oh you can deduct your computer", "You can deduct books you purchase as inspiration." ... "You can deduct this... you can deduct that...." Everytime anything came up throughout the semester she'd add, "Don't forget, it's tax deductible!"

Then at the end of the semester she had us all over to her house for tea. She showed us her studio, her published work, and then she showed us a painting she did of the worst year of her life. It was a painting about being audited by the IRS. She said it was the single most horrific thing she'd ever gone through.

After that I sort of threw out all of the advice she gave about deducting everything.
