BWILC is, hands down, the best book on trading imaginable. It took me quite a few days to read the e-book. I spent an entire weekend reading (and still had more to go), going through the chapters. I'm glad I did as it laid the foundation for a rational approach to trading. It wasn't the first investment I made in my pursuit of a forex trading career; it was the best. It opened my eyes and allowed me to begin to see the big picture and lead me to the mentorship program.
What rings out the most to me is the ability to step back. Being on the hill observing the traffic is far more advantageous than being on the soft shoulder. This is what it boils down to. And this is exactly what BWILC depicts.
