The Israelites had this "everyone else is doing it" attitude too.
We want a king over us. Then we will be like all the other nations, with a king to lead us and to go out before us and fight our battles. 1 Samuel 8:20
The Israelites started looking around at the surrounding nations,and they noticed that all these other nations had a king. They went to Samuel and said, "Give us a king to lead us." (1 Sam. 8:6) Their request may have seemed legitimate, but it wasn't God's plan for them. The nation of Israel was established by God. They were His people and He was their God. God, alone, was to be their king. By wanting to be like the other nations, they were going outside of God's will and plan.
There is a way that seems right to a man, but in the end it leads to death. Proverbs 14:12
Just because everyone else is doing something doesn't mean it's right for me or you. We have to trust that God has a plan and His way is best. Instead of saying, "everyone else is doing it," we should should ask, "Does God want me to do this?"
Let God, not the crowd, guide you today.
