Inspired by our leader  I am planning to have my first 2-days solo retreat next weekend. Basically, do "do nothing" meditation, mindfulness through labeling, concentration, some kind of self-inquiry. 
No internet, computer, phone, writing, reading − just be for 2 days.
I am planning to do intermittent fasting and cook for this period on Friday. Also, I am thinking about going to walk for an hour or so in a forest every day. How does it sound? Does it make sense to do such a short retreat? Any advice? PS: I am planning to go to Vipassana retreat in April. Maybe, it will help to prepare.
