I played 7 years football. Why did I quit ?

I am currently 16 years old.
I started playing football at 7 and I stopped playing it at 14.

I still play football of course, but I am not doing proper training.
I just play with my friends.

With the 7 years I have played every position on the field.

I have been Goalkeeper, defender, midfielder, forward.

The best I was at defender and there I was the longest.

But why did  I stop playing football ?

Well I had pneumonia, and I had to be in bed for a month.

After the pneumonia, when I was OK.

I had a really weak stamina, and I was super lazy so I never bothered to start training my stamina up again, because people told me it would take alot of work and effort.

Before the pneumonia I used to be the best long distance runner in my class aswell, but now I can't run a long distance.

And to make it short,

I am lazy.
