These are some principles I try to imbibe in my life

• Thinking from First Principles
• Generalising and building a mental lattice from different fields(perspectives)
• The Last time Psychology ( Do everything thinking that you're doing it for the last time)
• Ego is the enemy(Just give me the raw feedback without all the shit sandwich around it)
• Take a Long view( if something's worrying you just fast forward 20 years ahead and look would it bother) because long term thinking will benefit in almost all fields. (finite and infinite games)
• Force yourself to simplify every initiative, every product, every marketing - everything you do." - Keith Rabois
• Work first on Priorities in your calendar
