Why do I not like to practice play sports?

Well this is my first entry in English. In fact, I would like to practice a little more English writing English a little more.
I'm doing an English course here in Lanzarote, Canary Islands. Yesterday we were practicing our vocabulary on sports and someone asked me for what my favourite sport is. I then realized that I don't like practicing playing sports.

I think I'm a lazy person. I don't like practicing playing sports because I've never had the chance to improve my physical skills. When I was at the in school and I was younger than I am now, I've never been choosing chosen for being to be in one time team or another. The captains of the teams on the gymnastics class let left me for his last chance pick. That was really painful for me. and I accepted that I was bad from then on and no matter how much effort I put forward, I would be always be as bad as they thought I was.

The years have passed and I've never tried again to enrol myself on any other teams or to try another sport as a new experience in life. Finally Lastly, I could also say that the experience made me become a lazy person who doesn't like sports because I'm not confident enough to put myself again in that situation of being chosen by one person again. I would like to say that I reckon that the person who had the problem was me not the people who chose me in the past as his/her last chance choice.

EDITORS NOTE: Great job :) I put play instead of practice because practice is when you are already on a team and have to meet with your team to go over different skills for that sport whereas play is the activity of playing the sport itself. Most problems were in the tenses (Past, Present, Future) but all in all well done :)
