Even though people say its quite costly, its meant for the rich, but I would love to play tennis one day.
I knew just a bit about this sport, but its not too hard to estimate the price. As an amateur, at least I should have a nice Nike or Adidas which up to now is about 50 USD, not to mention other fancy sportswear like T- shirt, shorts and socks. For equipment, bats, bat bags and also I should never forget safety equipment, sadly, its said that the higher it costs the better, so Im gonna give it around 200 USD. So that would be 250 USD in total. Quite expensive Im afraid. Anyway, my dad, who is not only motivated, but also knowledgeable about the sport, would definitely be my go-to partner. I guess the reason why Im into this quite-expensive sport firstly is because of its intense, intensive practice, intensive competitiveness, for example, which helps increase my patience and focus. In addition, such independent sport makes me feel rewarded, feel proud because what Ive won actually is myself.
