“How can I stop feeling guilty for not following the path/expectations/perceived expectations of frie asdfadsf ”

How can I stop feeling guilty for not following the path/expectations/perceived expectations of friends & family and be at ease with how I live and what I do with my time? So I didn't go to a top school, get a job in my exact major, or work all the time like a lot of people my age, but I am doing well in my career and am very happy. Why do I always seem to think I should be doing something else and can not be at ease doing what I am doing that I love??
