Why I keep repeating the same mistakes?
In essence, this is about the self wanting control, or more precisely, the illusion of self and control. I think this is exactly what Khenpo Sherab Sangpo meant when saying that teaching and experiencing are different things: nobody can just tell you that self and the control the self wants are illusions, it's something you need to experience.
This sounds extremely esoteric, but if you think about it, it's really not. You can't really convey any human experience to anyone else who hasn't had that experience, even something extremely simple like what coffee tastes like. You can only use words to try to convey the experience, but words are limited and often have associations unrelated to the experience you're trying to convey.
The first step I would recommend you to take is to stop labeling the process as a mistake, as this gives cause to negative feelings. Try to observe the chain of mental causation that leads to procrastinating or &quot;mistakes&quot;. Do not judge or try to analyze, just become aware of the process. After a while, you will see that there is &quot;space&quot; between the arising thoughts and the feelings they invoke. Again, this is something you need to learn to experience, not just be told. The first phase of meditation is, in essence, to become aware of this process and learn to observe it without judging or reacting to it from those spaces in arising thoughts. Only after you've become comfortable with this can you turn to the &quot;why&quot; behind this process.
Hope this helps.
