What do you guys do when you can't get motivated to code and feel sluggish?

Read devRant.

Sleep for hours

I don't code on that day 😂

I'll just do something I actually enjoy, relax a little.
But sometimes I really need to work even though I don't feel like it, so I'll just reward myself with some whiskey and a steak after I'm done :)

I find my coding motivation peaks and ebbs through out the day.

When it ebbs I usually take a 10 minute break and read something. Or I switch projects and do 10 mins on a fun side project. I am pretty strict about the 10 min thing and jump back into the main thing whether I wrote 10 lines or 2 lines...

@bigus-dickus line for line would be the perfect software development model.

Take a break and Devrant / read a programming book or answer Stackoverflow questions I guess.
