I would take it even further and say you are what you experience.

Our reactions to our experience is what shapes our lives. I guess this is sort of a buddhist perspective.

I feel like I am going through this issue of not knowing who I am, myself at the moment. When it comes to work, I just don't enjoy it anymore. And I have always loved programming!

I kind of get the feeling that if we can't be happy now, in this moment, then no amount of change will make us that way. It is all perspective.
