power of observation

if you somehow stand through 100 surgeries, I bet you will become some sort of a dependable assistant surgeon yourself whatever be your qualification or background. 

.....such is the power of observation. 

The same is true about trading. 

If you stand through 100 swings or trades you can surely become a decent trader with decent results. 

The trouble is we go through 100s and 1000s of trade surgeries but not as an observer but as a patient with mind under anesthesia.....
