When we lack confidence, feeling unsure of ourselves, peer pressure can be very hard to resist. A lack of sureness or confidence makes people more susceptible to peer pressure. After all, peer pressure can affect people when it comes to very important issues, including their view of premarital sex, drug abuse, and even the goals they will pursue in life. If we allow ourselves to adopt the “group norm” when it comes to such issues, we could drastically affect our own future. Peer pressure can be both positive and negative. It’s usually the negative peer pressure that gets the most attention.
