Came here to say this, on both counts.

Quitting smoking was the hardest thing I ever had to do.

You did the right thing. 
I've never been a smoker though I was close to becoming one but my job as teacher didn't really allow me. I still smoke but only a few times a year and mostly in winters and when I'm travelling alone.

What is something you regret doing when you were younger?

I regret smoking cigarettes. I'm happy I quit. 

I also regret the times in which I've treated people poorly, especially when they didn't deserve it.
