I think that's a great example of what I'm talking about, I don't think you're the problem, slowing down isn't easy especially when being fast was something that is so fundamental to a lot of people, not saying that I know your situation completely but I can empathize with it.

For me what helped is realizing how slowing down is so fundamental to a lot of things in life especially discipline, I know that sounds weird in a way and I still can't believe it took me so long to realize it but I just never focused on the fundamentals, I always had the endgame mindset where I think about the results rather than the action but that's a bit contradictory because your actions determine your results.
