I started using Headspace a few months ago. I've noticed a pretty positive effect.

I react a lot better to stress. On days at work when I was in tough situations, my mind would be racing for the whole day and I wouldn't be able to sleep. I feel like now, I can clear my thoughts and focus on what I should be focusing on.

I am very calm when in situations where I used to get angry(video games, lol).

I used to have major insomnia, now I can get to bed a little bit earlier. I'm still working on this part.
