As with all types of photography, smart business sense is key. There are many ways to make a living with travel photography, and much of it extends well beyond your photo gear into social media marketing, content development, negotiation and sales. But the first step is to get out into the world and shoot. Start with anyplace you've been dreaming of traveling, and go! Plan ahead, do some research, and don't shoot like a tourist. Can't afford to travel? Search for opportunities in your nearest city to begin building your portfolio.

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!
