Congratulations, you are a sentient and sapient being!
You'll enjoy such wonders as introspection, self-modification, and identity.
The key to all of these is self-awareness. Self-awareness, as the name implies, is being aware of yourself. I know Me. I am the only one that can know Me directly. I must seek patterns in My behaviour, My feelings, My knowledge.
The more self-awareness, I have, the better. It allows me to understand and interpret Myself, look for areas in which change is needed or desired, and watch for the effect of those changes.
