I don’t know if you are interested in learning or practising new things time to time. As soon as we want to move to a new (or different) area (or job for instance) we need to learn new subjects.
Furthermore, you should remember from school that you were good at maths (or whatever) but you weren’t good at running. Then in your current life you are extremely good at something and regular (or really bad haha) at others. You think this is ok with everyone so you don’t need to worry about to improve your weak areas. If you think you wouldn’t be able to improve your weak skills you have a fixed mindset. It means, your mindset doesn’t accept you are able to improve any your skills.
There are other people that don’t care about their weakness. In fact, they consider that they would be able to improve any skills.
I found this great book called
Mindset – Changing The Way You think To Fulfil Your Potential
by Carol Dweck
In this book you will find many examples of acting under fixed and growth mindset.
For instance, I have been practising Crossfit since April. At the beginning I was in a basic level but with the help of coaches and my crossfiters (this is the name for us) I have improved a lot of. Indeed, I´m the older guy in the box (this is the name for the place of practising Crossfit) but my age haven’t blocked to improve step by step each exercise.
One of the guys there told me once: Mario you are our inspiration. If you can do an exercise we should do it as well without any excuses.
To sum it up, go ahead to buy this awesome book and I hope you discover what kind of mindset you have. Keep in mind, you always would be able to improve any aspect of your life if you have a growth mindset.
