Very early in the morning. I arrive around 6 am at the office; it is quiet with the least distractions and my head still fresh. By the time office rush hours begin I'm long done.
In the morning, right after I finish all the other items in my morning work routine. Coffee or teas, water, and headphones ready to dive in
For me the best time is after my kiddo goes to sleep at 7:30pm but most of the time I'm too tired to want to acomplish anything so I end up curled up on the couch watching tv
