The question was simply what's more important: some exam or quitting pmo. Not how many years you've "wasted". As per stress, you can probably say it's one of the reasons. But for me, more accurate is "stress is part of the cluster" that makes you procrastinate. It's the mortar between bricks of any form of negativity. It's the cause And effect in one. Acidic environment of procrastination cancer.Take away stress, and whole constuction falls down. Disintegrates. And -- in my experience -- there is only one way to take away the stress: learning there is nothing to stress about. I can see the sequence here: fuck up > stress caused by fuck-up > more fuck ups > self loathing > porn > stress from failure > another fuckup > self loathing > more stress > more fuck-ups etc. There is no beginning and no end of this cycle. It self-perpetuates itself ad infinitum. Fuck-ups happen as long as you're stressed, so you won't stop fuck-ups as long as stress component is there. The way I do it, is take it down bit by bit through mindfulness "exercises". Being concsious whenever I can. The more of those conscious moments, the less stress, the less stress the less fuck-ups, the less fuck-ups the less stress and so on and on. It's a vicious circle in reverse. Rewinding the tape. I personally don't "work" on my stress, or my pmo, or my self-esteem. There is nothing to work on, or nothing to learn... other then learning there is nothing to learn. To me it's more a process of un-learning what is not important until all that's left is important. Nothing. Unlearning who I'm not, rather than learning who I am.... I don't really know how to get through your wall, so I will leave it until (and "if") I find a better way.
