Another types of Motivation

There are different kinds of motivation of someone motivated by family, friends, someone to motivate what is deeds, my motivated was an anger! when I was in 5th grade and walked home from school. on the way home I was approached by three guys and they told me to give them my cell phone, I refused and they attacked me. I was not able to overcome them, and they beat me. I lay at home a couple of days all the wounds, and I realized that I should start to do sports so I could fight back to them the next time, so I signed up for judo. When I was doing and thinking only about how to take revenge on them and that motivated me when I hurt the whole body, or when I do not want to go to training, I knew that if I miss a workout, I can not take revenge on these guys
