Orson Welles co-wrote, produced, directed, and starred in "Citizen Kane" when he was 26 years old. It's OK, all you folks in your mid- to late-20s, don't despair: it depresses me too. But I don't want you to feel bad for wasting your 20s, I really want you to realize you basically wasted your teen years as well. You have to hear about these 19 kids who didn't waste their youth like I did.

Kenyan teen's invention saves lions, helps farmers

13-year-old Kenyan inventor Richard Turere used broken LED flashlights to create a lighting system that tricks lions into thinking humans are patrolling the area, which is enough to keep the lions away, protecting his family's livestock (and their lives) and reducing risk of human-wildlife conflict. I once figured out how to work the S-O-S setting on my flashlight, impressing absolutely no one.

16-year-old creates wildlife tracker website

16-year old Nadav Ossendryver created Kruger Sightings, a wildlife tracker website that provides real-time animal sightings for Kruger National Park in South Africa.

Jason Li, a 15-year-old high school sophomore, and his friends run the website iReTron.com where people can sell their old phones, laptops, game systems and many other gadgets and accessories to keep them out of the landfill.

Jarilla Mountains

After noticing some unusual new equipment near the Jarilla Mountains in New Mexico, 10-year-old Caitlyn Larson and her parents discovered a foreign company was planning to strip the mountain and send 6 million tons of ore to China. They rallied opposition and eventually helped the state of New Mexico realize that the new mining wasn't properly permitted, which has thus far saved the wildlife and vegetation that call the mountains home.

He said he wanted to save penguins. 'What are we going to do without animals?' he asked. If they die, we will all die." That's heavy stuff, Aghelos.

14-year-old designs and builds windmill to generate electricity

William Kamkwamba of Malawi, Africa, had to drop out of school in 2002, but he continued educating himself by reading science books and eventually teaching himself how to design and build windmills to provide electricity for his family. We first wrote about William in 2006, but he's since gone on to even greater things, such as writing a book, building a windmill to pump water for crop irrigation, giving a TED Talk on his experiences and even making an appearance on The Daily Show.

When she realized Jamba Juice was serving smoothies in Styrofoam cups, she started a petition, which eventually gained 130,000 signatures and prompted the company to change its cups to a more sustainable material. Thank you, Mia for helping us adults be less terrible.

OK, I'll just stop there. We all know there are so many more super kids who have done incredible things that will just make us feel less accomplished. Now that we're sufficiently demoralized, let's go out and show these kids what adults with more money, education and power can accomplish! Let's show these kids who's boss!
