Having a monologue is like dialoguing with a GPT, be glad you don't have one, that's just a way to bullshit yourself.
Learning to think is dangerous, and not recommended to anyone in its right mind.
Thinking properly is a higher mental process that emerge naturally at its own pace once you are in a "safe" state of mind and "safe" environment.
Once you are in a "safe" state, you can promote its emergence by allocating some slot of time to explore by "doing" (or trying to do at first) things yourself (initiative must come from yourself).
Exposing yourself to a various ideas when in an "unsafe" state is a bad idea that will most likely get you to a worse state. Learning (and thinking) is fundamentally based on rewarding, and if you try it in the wild, it's like starting a game in hard mode and going for the final boss, you'll just get your ass kicked down and learn nothing.
Thinking is nothing new, you can read "Meditations" by Marcus Aurelius, or write your owns. Just don't expect much, every one of your own thought have probably already been thought about, and joining a collaborative thought effort in search of wisdom will most likely require you to just be a passive consumer.
