Time passes by too quickly?
It is panic-worthy for sure.
Thinking can do it for me.
Lots of things. An important meeting the next day. Getting ready to travel. An argument with my wife. Basically anything that engages the mind and starts it racing. :)
Not being able to turn off my brain or getting behind in work and playing catch up.
Insomnia, my phone, and my inability to shut my brain off

Lack of sleep
Sleep nights are the ones before exams!!!
