lol, i remember visiting stockholm way back in 04', and even then, the, "cultural enrichment" had taken hold. stockholm at night back then looked like nigeria or egypt lol. i can't imagine what stockholm looks like today.
as for my biggest challenge, i used to have a speech impediment as a child. it's pretty tough when you're afraid to open your mouth out of fear of being ridiculed, yet you have to speak to function in the world. anyway, i've long since gotten past that, but it was a very difficult thing to deal with as a kid.
