How to grow mentally (with few suggestions):
1. Read books (The secrets)
2. Listen to podcasts about human psychology (Jordan peterson)
3. Listen to monks (sadhguru) & religious leaders (Apostle selman) 4. Ask questions (Google)
5. Be kind to people(colleagues, cleaners, waiters)
Bravery and courage are required to do anything meaningful in life.
remember when you started crawling,walking,talking,going to school,learning a new skill,asking out your first ex for a relationship etc
NO ONE HAS EVER BEEN COMPLETELY READY FOR GROWTH
