People talk about peer pressure as if it’s a bad thing (he started smoking because of peer pressure). The thing to keep in mind is that in many cases peer pressure is a good thing.
If you surround yourself with high achievers you will feel pressured (in a good way hopefully) to achieve great things.
If you surround yourself with people who eat primarily healthy food you will be more likely to start eating healthy foods.
If you surround yourself with people who read instead of watching TV you will more likely start reading (so you can talk about the same type of things as your peers)
The thing to remember is you do get to pick your peers. If you choose wisely you can all help each other to do things that none of you might do individually.
Just something to think about.
Have a great day!
