Please try your best to narrow it down to THREE! Can you recall which shows on TV feel synonymous with your youth? Can be your childhood phase, your adolescent phase, etc. - whatever you define as your youth!
For me: Jackie Chan Adventures, The Fresh Prince of Bel Air, Pokemon
Sliders
The Tomorrow People
Family Ties
Honestly, I read a lot more than I watched tv. There are tons of books that shaped me, but I had to struggle to remember the shows that helped me along.
