In general there are two types of human’s mindset with different traits that are completely different. There are humans with a growth mindset and other humans with a fixed mindset. A people who have a fixed mindset believes that they have limitations in learning and they are the way they are without improving their weakness. While the growth mindset learners believe that their learning ability is unlimited and they focus on their weak areas and try to improve it. Personally, I see my self-learning with a growth mindset side and there are some situation I have a fixed mindset on.
A specific thing that I would say I have fixed mindset on is my sleep hours. I disregard my sleeping hours due to study and stressful predicaments.
