As you grow and change as a person, your desires, goals, and interests will inevitably grow and change as well.
The attitudes, opinions, and behaviors that used to work for you, or that seemed to work for you, no longer will.
Your perspective will shift and you will seek out new circumstances and relationships that better align with who you are becoming.
You may find, however, that although your environment and associations have changed, you are no more happy or content than you were before.
This is because, as you pursue new interests, there is a risk of taking your old attitudes, opinions, and behaviors with you.
Take stock of this, be honest with yourself, and become willing to let go of those things inside of you that no longer serve you or who you want to become, and then you will truly have a new life.
