Leisure Activities

My relationship with sports was good when I went to school, I liked to run and I was the fastest of my class, I also played soccer and I even won some medals. But when I started to grow, that desire and energy diminished, so now I don't practice any sport.
The only physical activity that I like to do is ride a bicycle because it helps me to clear up. I have also thought about doing sports more related to self defense such as taekwondo or karate because it could be useful for a dangerous situation.
I think I should do more sport, but I don't like it very much, because I get tired very quickly and in this moment of my life I don´t have so much time for make physical activity in a permanent way.

But, if I had to talk about some leisure activity that I like to do a lot, that would be to draw and paint. Since I was a child I started doing it and since there, I never stoped, (even in a corner of the notebook while I'm in classes).
On the other hand, I started painting a little while ago, like 4 years ago and everything I've painted has been very self-taught. I have never been able to take professional classes, but I would love to take a workshop for learn techniques, the proportions of the body and everything possible. So, it would be more than just a "leisure activity".
