The Science of well-being

I just completed this amazing course from Yale – called the “The Science of Well-Being”. It was a great course and I wanted to share my learnings here:

Knowing is not enough – A lot of times we know what is good or bad for us but don’t end up doing it. It is the practice that counts. Practice is everything.

Mis-wanting – The things we think will make us happy don’t really make so much…

Leadership and other business Gyaan

Berkshire Hathaway’s Ajit Jain once said he likes working with Warren Buffet because Buffet “gives importance to the quality of decisions made before the outcome is known and not to the outcome itself.” However, it’s tough to assess the quality of decisions.  #integrity #leadership

“Remember me when I am gone away, Gone far away into the silent land; When you can no more hold me by the hand, Nor I half turn to go yet turning stay.

Remember me when no more day by day You tell me of our future that you plann’d: Only remember me; you understand It will be late to counsel then or pray.

Yet if you should forget me for a while And afterwards remember, do not grieve: For if the…

​वेख फरीदा मिट्टी खुल्ली, (कबर) मिट्टी उत्ते मिट्टी डुली; (लाश)

ChakrVyuh – beautiful poem in Ardh Satya

चक्रव्यूह मे घुसने से पहले कौन था मैं और कैसा था यह मुझे याद ही ना रहेगा

चक्रव्यूह मे घुसने के बाद मेरे और चक्रव्यूह के बीच सिर्फ़ एक जानलेवा निकटता थी इसका मुझे पता ही न चलेगा

चक्रव्यूह से निकलने के बाद मैं मुक्त हो जाऊँ भले ही फ़िर भी चक्रव्यूह की रचना मे फर्क ही ना पड़ेगा

मरुँ या मारू मारा जाऊं या जान से मार दूँ इसका फ़ैसला कभी ना हो पायेगा

सोया हुआ आदमी जब नींद से उठ कर चलना शुरू करता हैं तब सपनों का संसार…
