Thank you for asking!
I've thought about this question a lot.
I think awareness is the first thing and a major key piece to everything in our lives. Many people aren't even aware they aren't aware of themselves. I was certainly there myself at one point.
I also believe this is a lifelong process we do, rather than an event that happens.
I also don't think it's a requirement for everyone.
I do believe it's a requirement if we want more out of our lives and relationships though.
It starts with getting very clear on what you like and don't like for yourself and about yourself and facing those things. Much of this is also emotional and not something many people have talked about or worked on or even understand completely.
The things you like and don't like in your life, job, home, relationships, etc.
Deciding on the things you may like to change and the things you don't.
Then going to work on maybe 1 thing at a time to try to understand and/or change things.
There's also a big, but subtle difference between intellectually understand and doing these things, and emotionally embracing it.
All of this is a continuous process and much of it is emotional work because we often don't want to feel the emotions associated with things we don't like about ourselves or our lives.
I think we know when we've found a true version of ourselves when we're aware of where we are emotionally most of the time. We love and take care of ourselves emotionally and physically. We don't need anything else in our lives to make us happy. Meaning our main focus is internal and how we feel about ourselves, not on outside circumstances.
This doesn't mean we don't work hard, strive for more, give to things and simply want more out of our lives. But we don't need it or use it to justify our emotions or coping mechanisms.
I also must mention being kind to other people, which is very different than being nice. Being kind holds healthy boundaries with yourself and with others, while people pleasing is being nice.
This is by no means a complete list or strategy, but it's a start. Hope this helps and is what you were asking for.
Happy to clarify on this as well.
