Is the environment more important than willpower for us ?

I will give some examples

If I'm at home, I can't study. It's literally not impossible. I will sit there browsing the internet all day long for 9 hours straight.

The solution for me is to go to a library. I instantly become focused. Just the sheer environment of books and seeing other people study flips a switch.

If I'm in my room and my phone or my laptop is in my room and I want to get to rest, I can't come to rest. The solution here seems to be to leave all technical devices out of the room. The only problem is that I will get bored really fast. For this precise reason, I'm probably gonna buy - get this - an mp3 player. A device that can play podcasts, audiobooks and music but that doesn't allow for mindless browsing on the internet or checking messages.
