How we perceive and respond to peer pressure is closely linked with the choices we make, how we develop, and our wellbeing. When we don't know how to respond to peer pressure it can lead us to do things that aren't right for us or our situation. It's important to reflect on your own personal values and preferences and make decisions based on those rather than pressure.
