The other night, before I slept, I found myself scrolling through apps on my phone. Have you ever done this? 

I was exhausted.  
My body was ready for sleep.
My mind was ready to sleep.

Yet, my fingers kept scrolling. As if they were searching for some mythical fountain of youth.  

I paused.  
I asked myself, "what is this for?"

The answer is simple - self-efficacy. Scrolling is for the feeling of accomplishment - "I found something!" It's for the dopamine hit that comes from completing a task.  

When I came to this realization, I reminded myself of what I accomplished that day - the reasons I had earned an invitation to do it again the next day.

Then, I fell asleep.
