What I like to do

I work as a swimming coach in my neighborhood. Influenced by my job, I became to like swimming recently.
Actually, I had learned swimming for four years from six-year-old. Therefore I can swim a little, but there was about eight years wthout swimming, and my swimming skill was failing.
Especially I became poor at the butterfly. I felt very tired after my first swimming the butterfly in my gym. Very very tired, so next day I had muscular pain.

In this October, I was given a new program for work from my chief. The name was "Breaststroke and butterfly in 30 minutes", it means that I must teach butterfly, moreover I have to teach it to adult customers!! It also means that I have to show them a good example of butterfly.
Please imagine. If teacher is bad at swimming, how do you feel?? The customers must be disappointed in me, and they'll never join my program!!

Then I decided to be good at swimming, so I often practice after the gym is closed. At first, it was hard, but I feel very delightful recently!! To be good at butterfly changed from duty to fun, and now I am always looking for the closing time of gym when I work!!!!
