I absolutely agree with the gentleman in the video, if you live in "what if's" it will tare you apart, everyone can look at a chart a day later and look like a genius, thing is there is always another trade or opportunity around the corner, you just have to make yourself available for it, and if you cant or don't DONT think "what if i did" its irrelevant, move on, next thing.

For instance, what if this train strike didnt happen i would be at work, yet im not and am here, is what it is.
