Happy for their growth
Real friends just love it when their own friends grow as people and are successful in whatever they do. There is no jealousy there, they just want the best for you and would love it if you were a superstar. We mean at the end of the day it only helps them as well.
Because they are your friends, if you are successful it means you can share some of that with them. So it means that all the positivity spreads around and affects them in a good way as well. It’s nothing selfish, it’s just the power of healthy friendship and being there for them from day one.
