Rob Engle and Clive Granger discuss about the importance of good ideas for doing productive work. [youtube https://www.youtube.com/watch?v=bc98Tmqmjkk&hl=en_US&fs=1&rel=0&w=400&h=300] Some thoughts from Engle’s talk : To see what is in front of one’s nose requires a constant struggle  To select well among old things is almost equal to inventing new things  The universe is full of magical things, patiently waiting for our wits to grow sharper

Via Leo Babauta You can’t change your entire life. You can only change your next action. — You can’t change a relationship with a loved one. You can only change your next interaction. — You can’t change your entire job. You can only change your next task. — You can’t change your body composition. You can only change your next meal. — You can’t change your fitness level. You can only start moving.

My Yoga teacher suggested me to go through some talks by Sadhguru and particularly on Isha Yoga and Isha Foundation. Some of the videos are available on the internet Well, as usual I was pretty sceptical about the so called guru culture and the kind of double lives that they lead, as portrayed by the media. Till Date I had never heard of Sadhguru and only because my teacher asked me to read about him / listen to him, I tried looking him up on the net.

There are two issues which have been occupying my mind ever since the trades that I had suggested have gone wrong.

Is the spread really a result of cointegrated time series ?
