This is a great lesson! Taekwondo is a lifestyle. Just think about it the first 3-4 years is working towards black belt. None of this is next level stuff. Its stance, position, pressure, focus, respect, form, one-step, front snap kick, roundhouse, back kick, side kick, spin kick, etc. It takes what maybe 2 years to get a halfway decent spin kick but you probably are still searching for power or the ability to execute it quickly in sparing. So you need to build up your skills and maintain them over years of training. Eat healthy, get quality sleep, avoid injury. Since i started taekwondo later in life there is a ceiling for me but if i dont work hard every day i will never find out where that ceiling is. Always working and striving for more thats who we are!
