Why can't I please my parents?

I don't know if this fits into your problem but from my experience some parents have an idea of their children from the child's birth. They make expectations that their children can't or don't feel like they should follow. Maybe your parents have similar expectations and they're trying to fit you into a mold that you don't fit in.

It's literally impossible to please everyone all the time, your parents included. They are of a different generation and so have different values, perspectives, expectations and dreams. All parents do the best job they can

Parental expectations often conflict with our own desires. This may be because our interests and strengths do not match what our parents' expectations, or possibly what their "vision" of who they wanted you to be aligns with our own. The best course of action is to keep an open dialogue

A lot of our parents in this generation has grown up with completely different values and mindsets. It's not that long back, that it was legal to hit your children. That mindset is something that is crucial to our thinking nowadays, that someone would be able to hit their children. That is just an example of many, of how different a lot of parents have grown up, in terms of their children. A lot of our parents had different views and goals than we had, not only for themselves but also for us, the newer generation. That is why I believe it's hard for some to be able to live up to the standards that their parents have or had. But everything begins with a good dialogue. Sit down with your parents on a good evening, and talk to them. Pour out your perspectives on life. See if that could change anything. I'll just say that it certainly did for me.
