For reference, I am a 30 years old guy with no girlfriend, and I am spending the majority of my time working on my tennis. I'm sure there is an element of me trying to avoid life responsibilities but I also really like the sport and I am trying to improve while I am still somewhat young. The issue is my parents like to criticize me for doing this, they feel like I am wasting time and I feel very disappointed. Anyone has gone through this before?
