Oh gosh, that's 36 hours in the air, Hans? Ouch!! I'm counting total transit time -- for example, a flight I almost booked from Amsterdam to Cape Town had a 2 hour hop to Vienna with an 11 hour layover, followed by a 6.5 hour flight to Ethiopia with a 17 hour layover, followed by a 9 hour flight to Cape Town. Total transit = 45+ hours. Pretty rough!
Lyn's last tip is to have your own website. "Show off your work on Instagram and Facebook, but do ensure you have a good, easy to use website too. It should have some of your best work (with lots of keywords!), any specialities, and awards/competitions you have won, and your contact details. It's too easy to get carried away, add thousands of images, and forget the basics. Keep it simple."
