One of the best shows on television right now for teens and their families is MTV’s “When I Was 17.” It’s as simple as the title. Celebrities talk about what they were doing when they were 17 years old. Participants include Drake, Kevin Jonas, Katharine McPhee, Bret Michaels, Queen Latifah, and Lucacris. Whether the stories they tell are about big dreams and opportunities or big fears and failures or both, they are utterly engrossing and inspiring. And they are ideal lead-ins to important conversations about hard work, ambition, taking chances, and dealing with consequences.
