The impact of fixed mindset on stress and procrastination

In the small section where Carol Dweck talks about ideals, she's focusing on unrealistic goals that parents give children, but there's something that I found very interesting. She says students with the fixed mindset describe ideals that could not be worked towards. You had it or you didn't, and it suddenly hit me that one of the biggest problems of the fixed mindset is that you set impossible goals. You can't achieve something if it's something that you can't work towards. If it's either you have it or you don't think, then there's nothing you can do, so why put forth an effort?

And then it goes on to say that these students experience things including procrastination and getting stressed out. And those two things stood out to me because one of the ways that I have problems with my creative output is generally, throughout my life, procrastination. And I wonder if that's me reacting to the fixed mindset that I have an impossible goal and I'm expecting everything I do to achieve this impossible goal, and when I know that it can't, I procrastinate so that I don't have to feel the feeling of failure.

And the stressed out thing is something I underlined too because I wondered, actually as I was journaling this morning, I wondered when I transitioned from a younger man who saw himself as easygoing to a middle-aged man who is more and more stressed out easily by simple things, like my cat having digestive issues this week. Is my transition to a more stressed out mindset in some way related to vestiges of the fixed mindset that are ingrained in me?
