A thought:
If you got cool shoes, or a cool car, or cool clothes, but nobody is there to witness you wearing it or using it … does it make it still ‘cool’?
No.
Thus, we must have things or use things or wear things as if we were the only one to witness it or appreciate it.
For example, the reason I prefer to wear all black clothing is when I look at myself in the mirror, it is the most aesthetically pleasing to me. When I wear grey t-shirts, I don’t like it from an aesthetics perspective. And I also prefer all black shoes, because it is the least distracting to me when I am walking.
