Prague, and the rest of the Czech Republic, was beautiful! The Czechs have a love for living life that is different than any other country I've ever visited. I also can't forget to mention the food and my newfound love for smazeny (fried cheese).
The company I worked for has a focus in developing military simulations for various governments around the world. Knowing that the work I did would, directly or indirectly, protect and save the lives of soldiers was an amazing feeling.
What I wish was different
I wish that I had extended my stay past 3 months, as I shortened the trip in fear of becoming homesick. However, I quickly fell in love with the country and regret giving myself such a short time limit.
Look for internships outside of the country you reside in! There is so much more to be gained than just work experience.
