Final Takeaways
After hundreds of hours of reading, here’s what I’ve learned about self-improvement books:
Mindset comes before methods.
You don’t need more tactics—you need clarity of purpose.
Repetition beats intensity.
Real growth comes from applying one principle daily, not reading ten new books.
You are your best investment.
Each page is a mirror—if you read consciously, every book becomes a teacher.
