I sell physical prints mostly out of the fear of someone reselling. Like you said, they could still do that with a physical copy by scanning but at least that’s a little more of a hassle. I’d also hate to see my art printed on shitty paper or the colors are completely off because the buyer (or print service they use) doesn’t put in the effort to get the colors just right.
Numbers nerd. Guilty. I have always completely geeked out when working in Excel and creating spreadsheets that provide the information I need quickly and easily. I hate wasting my time in activities that do not add value and focus my efforts on being efficient as possible. My desire is to help others do the same! The files I create are tailored to the spreadsheet novice and do all the calculating for you. They are also always formatting to print out just right in case you need a hard copy.
