How do you continue to develop yourself as a manager ?

1. Continuously seek 360 degree feedback, accept it and work towards improving it - you own both the perception and the reality of the feedback as a leader
2. Provide mentorship to others (EMs, ICs, PMs)- put yourself in a position of being able to learn recurrently from other's experiences 
3. Delegate and auto-pilot your current team and take on more organizational responsibilities
4. Interviews and hiring - learn from experience of TLs and EMs from other companies
5. Read profusely
6. Prolific writer
7. Reflection and introspection
8. Re-read and re-write previous blogs
9. Networking with ex-colleagues, ex-team mates
10. Invest in weak connections
11. Follow the earnings call of big tech companies, understand their product strategy and direction
12. Follow the VCs, understand the startup ecosystem, S curves, network effects and the next bets
13. Pursue financial independence aggressively to decouple money and career
