Just like everyone else! One lemon at a time!
A teen is just another person. A younger person with their own age appropriate set of problems. Teens learn from their mistakes or problems just like adults and younger children. Some take a little longer than others, but they do learn in the end! The information they gather each time they have a problem will enable them to tackle the next problem a little more prepared. Sometimes they learn they should have or they shouldn't have, sometimes it is patience they learn, sometimes it is trust, or to not trust and rightfully so! Sometimes they learn listening to their parents was a good idea after all! Or they shouldn't have listened to their friends! Every Lemon is different! But each one adds to the lemonade!
