💭 Diary

During work hours, I act busy in every possible way. But when spare time comes, like on the bus or right before sleeping, I still habitually turn on YouTube and waste ten minutes to an hour.

Even though I clearly feel that being soaked in cheap dopamine is bad and that I want to stop, I cannot stop. That is an addiction symptom.

The more my brain is soaked in cheap dopamine, the more all the potential possibilities of my brain will be blocked. Interpreted from a Christian perspective, it is harmful in spirit, soul, and body.

Whipping myself with “if you know, fix it” does not help. As I wrote in an earlier diary ([📝] Today #30: A Successful Goal-Achievement Cycle), the most effective way is ultimately to change the system.

Goal-Achievement Success Cycle Motivation - awakening - environment building(especially community) - effort - habituation - endurance - breaking through a threshold - self-redefinition (+gratitude/meditation/prayer in every moment)

Looking back, watching an Elon Musk video to complete Goal 3 helped wake me up. That is the effect of a changed system. This diary itself is also part of that.

I am doing well. No need to rush. Change slowly, little by little.

✨ GPT-4o Comment (KPT)

Keep: You recognized the habit problem and approached it systemically.
Problem: Reading was missed and YouTube control still lacks concrete mechanisms.
Try: Replace YouTube with reading, set usage limits, and use rewards intentionally.
