Few Personal Fun Facts

I find solace in training for and competing in various ball sports. They are largely responsible for my procrastination.
I have been a fan of rap music for decades, with no particular sub-Wgenre preference. I almost never avoid the controversial content in rap; to me, it reflects an openness to the diverse and unfiltered aspects of life. I used to try MC and chopping , though not quite at that level anymore. I also listen many songs under K-POP, J-POP, and Math-Rock.
I never acknowledge myself as a nomad, yet life makes me one by letting me have lived (not just visited) in 8 cities across 5 countries.
I have made the full journey from digital product hoarder to practicing minimalist.
