Salary does not equate success. Get rid of that notion and your life will be much happier.
I know what my parents were earning. Both worked in the NHS, one a nurse who because a senior university lecturer, one a Surgeon. I work in the NHS, I will never be a nurse/lecturer or a Surgeon. Neither do I want to be. My parents pushed me to choose to do whatever I wanted to do that made me happy, regardless of salary. I did an arts based degree at first. Then went back to uni for radiography later in life. I don't consider myself to be unsuccessful because I don't earn as much or more than them. I am comfortable, not rich, not poor. I have a lovely home, lovely friends & family, I can buy myself nice things if I want to, treat my family & friends if I want to, go to nice places and nice holidays. I feel that is far more successful than my earning capacity. Not everybody can say they have those things, not even the very rich!
I don't find it a weird notion to talk to your parents about money, it was normal in our house. I find it weird your emphasis on more money = more successful. It's very patronising. Almost as if you think you are better than people who are earning less, even though they could be doing a more fulfilling and more essential job.
I was a student at 22, living alone, working 4 jobs, with £7 weekly food budget.
Obviously in your eyes I am a failure as I don't earn very much and can't give my children the best life possible! 🙄 Poor things.
