Airports stress me out, especially when I travel alone. I have rituals that help ease the anxiety, like a cup of chai and strategizing the perfect seat with a view of the gate, but away from the crowds, preferably at the end of an aisle without anyone facing me. Once I survive the airport, I make the most of my time on the plane. Of course, sketchbooks or regular books are nice to have on hand, but as an iPad addict, I have found ways to make the most of "my precious" while existing in Airplane mode.
For this trip, I downloaded several past issues of Professional Artist Magazine and their pocket guide, Financial Strategies for Artists. These digital versions are available for a fraction of the original price and so much of the information is still relevant even a few years after the publishing date. I picked up Feb/Mar 2014 for articles like Track Your Bottom Line and Adjust Your Career Course. May 2012 had How to Price Your Artwork and Organize Your Career. If you want something more timely, Offline Reader apps allow you to download webpages.
This is also a great time to catch up on boring, time intensive tasks like editing your reference photo library or just a time for brainstorming. If you read my post on Wunderlist, you know this is where I keep all of my creative inspirations and how I organize for future projects. In fact, I am writing this in my "Blog" section so I can post it later when I have an Internet connection.
If I want a more hands-on experience, I pull up the Brushes app. Technically, it is a drawing app, but mainly I use the layering feature for compositional problem solving on current projects or mashing reference photos for future paintings.
Even when you are away from the studio, there are ways you can improve your art business!
