I don't play video games, nor do I watch movies or television. I don't need mindless distractions in my life. I use one large monitor and split the screen to cross-reference code and documentation.

The code I write requires a lot of high level math and disciplined focus for prolonged periods. It requires intellectual engagement. The Pomodoro Technique helps me with focusing and also to take screen breaks for my eyes and general health.

What is your motivation? I study math in order to become a better programmer, and I become a better programmer in order to help my people in need.

I also use something called the Pomodoro Technique which is about concentrating for 25 minutes with breaks inbetween. There are apps and websites for this.

Learning math is hard work, it is boring and difficult a lot of the time, it is good to have a goal to motivate you.
