We all have to decide what works best for us. There is no right or wrong. Some people truly love what they are doing and want to do it forever. Others like change, regular and constant change. They get bored after some time and want to try and do different things. That is their choice for sure.
I worked at different places throughout my career. Finally, I wound up starting my own business and it was probably the happiest I ever was. Even then I retired, but am still as busy as ever. I am into new things and totally enjoying it.
But that is me. Each of you will find what works for and interests you. Go for it. Don't let anyone tell you differently. It's your life. Make the most of it and enjoy yourself along the way.
