Being a teenager means learning from your mistakes and applying all of you have learned throughout your years to real life. It means being scared to grow up because you don’t know what is on the other side of the closed doors. It means growing up without any choice, no ifs, and no buts.
Adolescence is a time for growth spurts and puberty changes. An adolescent may grow several inches in several months followed by a period of very slow growth, then have another growth spurt. Changes with puberty (sexual maturation) may happen gradually or several signs may become visible at the same time.
