Personal Interests to Balance out Life
So I understood it as that personal interests lie more in things that make your life better for yourself. So for example, it is not something you are interested in such as art but more about making choices in life that advantage you and only you.
Only thinking about how it will advantage me and only me without compromising will eventually make your life more balanced. So to be balanced, if you were for instance, thinking too much about the whole or someone else in the picture to care for, then stop. Take a step backwards, then take the whole picture out and just only think about the best of your current future.
It could be a selfish move. However, if you think it will benefit you, try it once it a while and see how you feel after.
For me, I decided to sleep later in the night because I tend to be a better thinker when it becomes later in the night.
I will take note and be mindful of acting on self interest for the being.
