Dude... 1) VNH, 2) I've read rants, and you sir, did not just post a rant...

A related exercise for sh!ts and giggles that I've found very helpful to break the tendency to focus on actions in isolate...

1) Go through HEM/PT and pick a hand that went to SD and had a > 20-30bb pot. Doesn't have to be yours. And shouldn't be all the time. Pick hands from people who represent all kinds of playing styles.
2) Start w/ pre-flop, bullet out every factor that would affect heroes decision -- stats, reads, position, blah blah. This obv includes thinking through ranges and the math involved. Then do the same for his actual PF decision - including what it means for his plan for the rest of the hand.
3) For the PF decision made, flip the script and take a moment to sit in vils seat. Bullet out a) how he could react and why and b) what the implications are of his actual reaction
4) Repeat all of this for every street
5) Assess the final outcome and decide whether you believe the actions were optimal, and most importantly...... why.

Rinse, repeat and above all, avoid shortcutting or skipping steps, for many hands.
