Hello!

I concur with Adrian's corrections, with two additional thoughts:

1. Your spelling of "practice" is correct in the United States.

2. If I were speaking informally, I would change your next-to-last sentence to say:

"I would rather study and watch TV on Sunday than hang around in a bar." 

However, your sentence makes me wonder: Do you generally study AND watch TV on Sunday? The two activities often conflict -- that is, it can be difficult to study with the TV on.

Do you mean to say, "I would rather study or watch TV on Sunday than hang around in a bar."
 

Things change every all the time

Today I was thinking about my/these last seven years. I perceive that I have changed (my mind) a lot.
Today/Now I have stopped drinking alcoholic beverages and I don't smokeing too either.
Today I pratise sports. I love running and trekking so much.
My life has changed, and now I live much better with my body.
I can do things very fast now that after I couldn't do before.
I prefer to study, and watching TV on Sunday than to stay in a bar.
Everything is an option question of choice and I have made did mine.

The same here, but I should have done it much earlier in my life.
