My surroundings are the result of my decisions. Accepting this is the birth of responsibility.
Thus, unless I truly understand myself, my personality, my past, my skills and shortcomings, my fears and illusions about my future and my truest desire for what I want out of life.. I will not know which decisions are truly in line with the results I want, and which decision are just a result of my ego getting in the way.
As an example: I used to have the burning desire to have a sports car. Nothing wrong with a sports car, but in that case I felt, I definitely need it. It was the quintessence of what I was aiming for. But the more I looked within I noticed that I wanted to own it as a act of defiance. Defiance of what others thought I was capable of, as a final act of rebellion, the "I told you so". While this is a fun thing to do, it definitely is not a good inspiriation to aspire towards. Its the ego guiding.
Using Jordan Peterson's selfauthoring program has put this pursuit on another level. I have written for many years in my notebooks and software, but never have I had so many "aha-moments" in a short period of time. This program is worth so much more then what it costs in €€€.
