Thats Tighten from the movie Megamind.

The spying will just be more in your face if anything.

Maybe look into bullet journaling? Its not as straight forword as just writing down your thoughts. Its a more intimidating form of journaling, but in a good way. When i used that method i found that its complex format did a really good job at filtering my thoughts. Which took a lot of weight off my shoulders, allowing me to put more focus into bettering myself.

Start by just writing what you did that day. When you woke up. What you ate. Who you interacted with. How you felt throught the day. Eventually you will start to open up to yourself. Thats when the words seem to start writing themselves.
