Playing four games yesterday show that I am progessing well with my stamina and it does feel great.
Initially thought that I only for a scratch on my elblow for doing a dive, I was surprised to find out that I got a sprain on my left wrist as well this morning... Furthermore, I could feel pain on my thigh as well while walking up the stairs to my office.
In the end, I have no regret on channelling all my energy through badminton. :P
